Is it permissible to supplicate for the fulfillment of a specific request (such as facilitating the completion of studies) when one does not know what is good in that request?

The matters for which a person supplicates are divided into two categories:

1. Supplication for something not permissible by Sharia: Such as supplicating for cutting off ties of kinship or facilitating forbidden acts. This is an aggression in supplication, which is blameworthy by Sharia, based on the words of Allah the Almighty: "Call upon your Lord humbly and secretly. Indeed, He does not like aggressors" [Al-A'raf:55], and the words of the Prophet, peace and blessings be upon him: "The supplication of a servant continues to be answered as long as he does not supplicate for a sin or cutting off ties of kinship."

2. Supplication for a permissible matter: Such as supplicating for marriage to a specific woman or completing one's education. This is among what Allah has commanded, for the servant is commanded to supplicate for the fulfillment of their needs, based on the words of Allah the Almighty: "Is not He [better than your gods] who responds to the desperate one when he calls upon Him and removes evil?" [An-Naml:62], and His words: "And your Lord says, 'Call upon Me; I will respond to you.'" [Ghafir:60]. The servant supplicates for what they believe to be beneficial, while realizing that what they perceive as beneficial might contain harm unknown to anyone but Allah, based on His words: "But perhaps you hate a thing and it is good for you; and perhaps you love a thing and it is bad for you. And Allah knows, while you know not." [Al-Baqarah:216].
