How to liberate Al-Aqsa through the lessons of the Battle of Ain Goliath

On the twenty-fifth of Ramadan, 658 AH, corresponding to the third of September, 1260 AD, the decisive Battle of Ain Jalut took place between the Muslims, led by the ruler of Egypt, Saif al-Din Qutuz, and the Mongols, led by Kitbuqa Nawin. God granted victory to the Muslims, decisively defeating the Mongols, and liberating the Levant and Palestine with a resounding victory from their filth, saving the Muslim nation and its civilization from destruction.
It is useful for Muslims today, both leaders and peoples, to understand the reasons behind their forefathers' victory over the undefeated Mongol army and to draw lessons from them, as they are extremely useful in our current struggle against the nation's enemies, chief among them the Jews. These are the most important reasons for the victory over the Mongols at Ain Jalut:

The Muslims were victorious because they found a faithful and brave leader who decided without hesitation to confront the Mongols. He was not intimidated by the reputation of their invincible army, nor by their unprecedented crimes of merciless killing of children, women and the elderly, their murder of more than a million Muslims in Baghdad, and their destruction of all signs of civilization there. He was not shaken by Hulagu's message to him, which read: "Learn from others, and submit your affairs to us, for we show no mercy to those who cry, nor pity those who complain. What land will shelter you? What road will save you? What country will protect you? You have no escape from our swords, and no escape from our majesty. Our fortresses are invincible, our armies are of no use in fighting us, and your prayers against us are unheard of." Rather, he ordered the killing of the Mongol messengers, cutting them in half and hanging them on the gates of Cairo. He allowed a young boy with them to return to tell the Mongols what he had seen, thus shaking their morale and raising the morale of the Muslims. This decision can only be made by faithful leaders who consider death - which the enemies threaten - as their highest aspiration.

Because Qutuz made his advisor a bold, militant scholar, Al-Izz ibn Abd al-Salam, who even advised him. He encouraged him to wage jihad and advised him not to impose taxes on the people for the sake of war, except after he and other Mamluks in Egypt handed over to the treasury all the money they had, even the jewelry and ornaments of their women. If that was not enough, he would take taxes from the people. The Mamluks responded to that and brought all their money, so the morale of the people rose and they rallied around their leadership.

- Because Qutuz was not influenced by the discouraging and obstructive leaders and princes who appear in times of danger, and present defeatist views. Rather, he insisted on his position, and announced it clearly, strongly, and frankly. He gathered the princes and notables, read Hulagu's letter to them, and asked for their opinion. They suggested fleeing Egypt or negotiating with the Mongols for surrender and submission, under the pretext of the enemy's military superiority, the country's weak economic capabilities, and the reality of the weak nation, which was now without a caliph. So, he incited them, reminded them of their honor and the principles of their religion, and said to them with full confidence: "By God, if I had no one to confront them with except myself, I would go out to them and fight them." Their souls were protected, they were encouraged, and they decided to fight with him. The decision that the people unanimously agreed upon was to go out to confront the Mongols in Palestine, and not to wait for them in Egypt.

Because the nation, with all its components, has united in jihad. The leaders, princes, and scholars are with the soldiers on the battlefield. It is impossible for the nation, with all its components, to unite around a goal and fail to achieve it.

Because the banner raised in the battle was the banner of Islam, and because the hearts and tongues of the soldiers and leaders were busy with prayer, remembrance, and supplication. When the two armies met, and Qutuz noticed the large number of Mongols, he ordered his soldiers not to start fighting until the preachers were on the pulpits, praying for them during the Friday prayer.

Because Qutuz got down from his horse that had been hit by an arrow, and began to prostrate to God Almighty, and dust his forehead with dirt, and shouted at the top of his voice: “O Islam!” “O God, support your servant Qutuz!” So the feelings of faith were stirred in the soldiers and princes, and humility increased, tears flowed, morale rose, and the battle was good. The Mongols were defeated and fled, and the Muslims pursued them until they destroyed most of their army, killed their leader, captured his son, and liberated all of Syria.

There are many lessons that can be learned from the Battle of Ain Jalut, but I will suffice with two of them:

First: The presence of the invading occupiers in the land of Muslims will be prolonged if the nation removes Islam from the battlefield with the enemy. This is what delayed the liberation of Palestine from the Jews in our time. However, if the nation brings Islam directly into the field of conflict with its enemies, the life of the occupation will be short. Palestine, which Qutuz came to with a faithful army raising the slogan “O Islam,” did not remain in the hands of the Mongols for more than five months, and Damascus did not remain under Mongol occupation for more than seven months and ten days.
Second: The great victory of the Muslims at Ain Jalut, over the world's most powerful armies at that time, came only about two years after the crushing military and moral defeat of the Muslims in Baghdad. This short period is not enough to rebuild, rehabilitate, and raise the morale of a defeated nation. Rather, it proves that the Ummah is always good, but it needs a serious, sincere, and struggling leadership that knows how to mobilize this goodness. The Ummah was defeated in Baghdad when Caliph Al-Musta'sim was careless, frivolous, and weak. And here is the same Ummah triumphing only two years later when it was blessed with a faithful, sincere, and struggling ruler. This is a lesson that Islamists of our time should be well aware of. They should not be reluctant to attain power under the pretext that the Ummah needs more preaching and education, because the Ummah is good, and the arrival of a strong leadership to rule the Ummah is what mobilizes the latent goodness within it, enabling it to restore its glories, defeat its enemies, and liberate its land.
