All perfect praise be to Allah the Lord of the Worlds. May His peace and blessings be upon Prophet Mohammad and upon all his family and companions.
Sterility isn`t a valid reason for the dissolution of the marriage contract, however, you should treat others as you like to be treated. Thus, if a man who has the same condition proposes to your sister or daughter, you wouldn`t approve that he hides the truth. The evidence on this is that 'Abdullah bin 'Amr bin Al-'As (May Allah be pleased with them) said: The Messenger of Allah (PBUH) said: "He who desires to be rescued from the fire of Hell and to enter Jannah,
should die in a state of complete belief in Allah and the Last Day, and should do unto others what he wishes to be done unto him." {Realted by Muslim}.
In conclusion, We (Iftaa` Department) advise you not to hide your condition and Allah will reward you with a pious wife, and remember that Abu Hurairah (May Allah be pleased with him) said: The Messenger of Allah (PBUH) said: "He who takes up arms against us is none of us; and he who cheats us is none of us." [Muslim]. And Allah The Almighty Knows Best.
