How can one reconcile the fatwa that prohibits praying for the impossible and what happened to a person who succeeded after failing by having their grades increased, with what is stated in "Al-Durr Al-Mukhtar" regarding the prohibition of asking for well-being for all eternity, the good of both worlds, and ordinary and legal impossibilities, taking into account the Prophet's (peace be upon him) supplication: "O Allah, I ask You for all good, the soon and the delayed, what I know of it and what I do not know," and the supplication of Zachariah (peace be upon him) for a child when he was old and his wife was barren, and the supplication of the Companions of the Cave?

The standard for a legitimate supplication is that it befit the glorification of Allah, the Most High, and that the supplicant be desirous of a response, fearful of falling short. The Muslim should undertake the means and ask Allah for assistance. If a calamity befalls, one must be patient, take the legitimate means, and supplicate for relief without proposing a specific manner that defies custom. The story of the companions of the cave and Zachariah (peace be upon him) is proof of this; Zachariah's supplication was for the continuation of the true religion, not for worldly gain, and prophets are supported by Allah through the breaking of customs. As for supplicating with "the best of both worlds" and "warding off their evil," it is permissible if one intends the good that Allah, the Most High, knows and which results in reward, for good may be in what a person dislikes and evil may be in what he loves.
