The effects of ‘Ayn Jaaloot Battle

Exalted Be Allaah! Although ‘Ayn Jaaloot was a single battle that lasted only one day, its effects were too strong to imagine, and too numerous to enumerate. The effects of ‘Ayn Jaaloot battle are too important to cover briefly here. Let us see some of them, and it is incumbent upon the scholars and analysts to scrutinize them in more detail.
The first effect:

The Muslims returned to Allaah the Almighty in the course of preparation for this battle, during it and afterwards, also this continued for a long time afterwards. The equation became clear-cut in the minds of the Muslims; when they moved far from Allaah the Almighty, the Tatars were granted authority over them; and when they returned to Allaah the Almighty, the result was the decisive victory which was considered miraculous in the sight of a lot of analysts. That is not strange in reality; the natural consequence of the return of the Muslims to Allaah the Almighty is that they should emerge victorious over their enemies.

It also became clear to the Muslims that the war was principally based on religious grounds. Many Christians allied with the Tatars, although their long-term interests were with the Muslims rather than the Tatars. The Tatars used to break their treaties, whereas the Muslims always respected theirs. That is an essential principle in their religion, a fact which their reality confirms along almost all their history; and the Muslims never committed a violation in terms of breaking the treaties, except in rare cases which had strong justifications.

For this reason, the Muslims became strongly convinced that their wars with the Tatars and the Christians were not only interest-based, as many Westerners, Secularists and Materialists like to depict, making the economy the main engine of wars, or the military and strategic purposes its fundamental aim. However, as we have already seen in this story, religion played a strong role in stimulating the Christians, and had a stronger effect on motivating the Muslims. Allaah the Almighty drew our attention to this fact many times in His Noble Book. For example, He says (what means): {And never will the Jews or the Christians approve of you until you follow their religion.} [Quran 2:120] Thus, their approval will only be attained by following their religion rather than the survival of their benefits.

He further says (what means): {And they will continue to fight you until they turn you back from your religion if they are able.} [Quran 2:217] He Clarified that fighting would inevitably continue until the Muslims leave their religion, and without that, by no means would the fight cease between them; and it would not be sufficient for the Jews, the Christians, the Tatars, the polytheists and the Hindus to take control over the territories, houses, possessions, petroleum and people. That is because the supreme goal of those would be to subdue or say "eliminate" the Islamic religion.

All Islamic movements, religious orientations, the attempt to change the curricula of the Muslims, and the media war on its different levels are but various expressive forms of strong aversion to the "existence" of religion rather than the existence of the forces and borders. In other words, the battle, in principle, is based on "existence". They do not accept the "existence" of the Islamic religion on the face of the earth. That is why the war would never cease, because the religion of Islam would never cease to exist, by the permission of Allaah the Almighty. Peace then is not fit for a strategic choice, under any circumstances, whatsoever. If you give up everything in return for peace, they will not accept it unless you give up your "religion".

The Muslims understood well, after ‘Ayn Jaaloot Battle, that the conflict was religious in the first place; and that if you liked to emerge victorious in this conflict, you should be religious, i.e. to entirely adhere to this religion (of Islam).
That is the first effect of the eternal Battle of ‘Ayn Jaaloot.

The second effect:
The Muslims, in ‘Ayn Jaaloot Battle, exterminated the hideous psychological defeat that they had long been suffering from, which we have already talked about in detail in the beginning of this book.

The Muslims emerged from the state of overwhelming frustration, and learnt that the hope in Allaah the Almighty would never cease, that the forces of the disbelievers, no matter how overpowering they might be, would inevitably vanish: {Be not deceived by the [uninhibited] movement of the disbelievers throughout the land. [It is but] a small enjoyment; then their [final] refuge is Hell, and wretched is the resting place.} [Quran 3:196-197]
After the Battle of ‘Ayn Jaaloot, it appeared clearly to the Muslims how Allaah the Almighty has power over all things, and nothing on earth or in heaven could stop Him.

It is true that they knew this fact theoretically before; however, the battle came to apply it, in such a way as to leave no doubt in the heart of anyone.
{And if Allaah Should Touch you with adversity, there is no remover of it except Him; and if He Intends for you good, then there is no repeller of His bounty. He Causes it to reach whom He Wills of His servants. And He Is The Forgiving, The Merciful.} [Quran 10:107]

The third effect:
The veneration of the Islamic Ummah was restored following sixty years of loss. After the Islamic Ummah, towards the end of the 6th century of Hijrah, had attained a great rank of victory, pride and sovereignty, in the wake of both victories of Hattin in the East, Palestine and Ark in the West, Andalusia, it underwent a severe breakdown with which it lost its veneration to the extent that the dogs started to bite its body, and the serpents started to move freely in its territory.

However, the Battle of ‘Ayn Jaaloot bestowed veneration and respect upon the Islamic Ummah, so much that Hulagu, who was settled in Tabriz along with a huge number of the Tatar forces, did not think of occupying the territories of Shaam once again. Rather, all he could do was dispatch a vindictive military expedition which attacked Aleppo and shed the blood of some of its inhabitants, with the intention just to confirm his presence. The veneration for the Islamic Ummah was inculcated in his breast, and he did not like to expose his army to another destructive war.
The veneration of the Ummah never returns but by means of such days as ‘Ayn Jaaloot.
Verily, Allaah wards off with the power of authority (of immorality and sins) what may not be prevented with the Quran.

The fourth effect:
The entire military force of the Tatars was destroyed in Shaam, Palestine and Turkey. No mention was heard about the Tatars in those regions for decades. The people came to entertain no oppression, injustice, onslaught, nor homelessness, and became secure with regards to their own selves, property, territories and honor. No one was able to frighten the Muslims in those regions for more than 140 years after the Battle of ‘Ayn Jaaloot, when the Tatar slayer, Tamerlane (Taymoor Lank) entered Ash-Shaam and invaded Aleppo and Damascus in 804 A.H., after invading the countries of the Eastern part of the Islamic world.

We shall talk about the events of Tamerlane, Allaah willing, when we come to the discussion of the Mamluk State and the Ottoman Caliphate. What concerns us now is that this Battle of ‘Ayn Jaaloot secured the Muslims for over 146 years.

The fifth effect:
The Battle of ‘Ayn Jaaloot gave birth to the great Mamluk State, which carried the flag of Islam for about three centuries, namely 270 years. It is true that the Mamluk State began its realm in 648 A.H., when Shajarat Ad-Durr took over and then was succeeded by her husband, ‘Izz Ad-Deen Aybak. However, it was the Battle of ‘Ayn Jaaloot which gave legitimacy to Mamluk power before all the Muslims. Within ten years, the Mamluks achieved two great victories over the enemies of Islam: the first was in Al-Mansoorah and Faariskoor in 648 A.H., over the armies of France led by Louis IX, and the other was in ‘Ayn Jaaloot (over the Tatars).

Although the general leadership in Al-Mansoorah and Faariskoor was Ayyubid, yet the army which fought was mainly Mamluk-based, whereas in ‘Ayn Jaaloot, the victory was entirely Mamluk. In this way, all the Muslims felt that the Mamluks were the most capable of leading the Islamic Ummah. And so, the Mamluk State was founded, and undertook the mission of repelling the attacks launched by the enemies of the Islamic Ummah, from among the Crusaders and the Tatars. It was indeed a Jihaad-based state most of the time.

Although the Mamluk State tried to make itself more legitimate, by hosting the Abbasid royal family in Cairo beginning from 659 A.H., in the wake of the Battle of ‘Ayn Jaaloot, and during the era of Ath-Thaahir Baybars, it did not represent the real Islamic caliphate, for, at its largest extension, it only had control over limited parts of the Islamic world, namely Egypt, Shaam, Hijaaz, Yemen, parts of Iraq and Libya. However, the remaining part of the Islamic world was distributed among different sects. The Muslims did not find the meaning of the real all-embracing Islamic caliphate which could gather all the Muslims before the foundation of the great Ottoman Caliphate which gathered the Muslims after long years of division.

Anyway, the Mamluk State, in its own time, was the strongest, the most serious and the most awesome of the Islamic world all.
That is why historians call the period in which the Mamluk State existed the "Mamluk era", thereby ignoring many small states that existed during this period.
