Qutuz, May Allaah have mercy upon him, did not come at a time of well-established power or sovereignty, nor under easy and good circumstances, nor did he rule the country while being strong and irresistible, nor did he sit on the throne at a time the resources of his state were countless. On the contrary, all circumstances were against him.

However, he sought the aid of Allaah, worked faithfully and sincerely, and urged others to work with him. For this reason, he had to attain the fruit of his work.
On the day the Muslims follow the example of Qutuz, May Allaah have mercy upon him, they will, inevitably, attain the same fruit he had attained. It is unnecessary for the change to take years, decades or centuries.
‘Ayn Jaaloot Battle broke out only 10 months after Qutuz, May Allaah Have mercy upon him, had taken over. What is important is to find the sincere, truthful, knowledgeable workers.
Allaah never fails His promise.
{Indeed, We Will Support Our messengers and those who believe during the life of this world and on the Day when the witnesses will stand.} [Quran 40:51]
