And let him make his desire great—note the doubled ẓāʾ in the verb—that is, he should persistently press his need.

“Nothing that He grants is too tremendous for Him”: nothing is so large or difficult as to tax Him.

Overall meaning of the ḥadīth: The Prophet ﷺ forbids attaching one’s plea for forgiveness and mercy to the divine will, and he commands that the request be made with firm resolve, free of any such condition. He explains that linking the request to Allah’s will gives the false impression that some of His servants’ needs might weigh upon Him or somehow compel Him to fulfill them—an idea wholly at odds with the truth, for He is the Self-Sufficient, the Praiseworthy, who does whatever He wills. It also suggests a certain coolness on the servant’s part and a feeling of independence from his Lord, whereas in reality he cannot dispense with Allah for the blink of an eye.

Connection between the ḥadīth and the chapter: the report contains a prohibition against tying one’s plea for forgiveness to the divine will and states the reason for that ruling.

Points derived from the ḥadīth:
1- It is forbidden to link one’s request from Allah to His will; instead, one must ask Him unconditionally.
2- Allah must be declared free of everything unbefitting Him, and His bounty is vast; His self-sufficiency, generosity, and munificence are perfect.
