“Once I was with abu ‘Abd Allah (a.s.), when a man came and said, ‘I pray to Allah to keep my soul in service for your cause, if two young men slept together and one has a son and the other has a daughter; if his son could marry the other man’s daughter.’ He (the narrator) has said that he (the Imam) said, ‘Yes, Allah is free of all defects, why can it be unlawful?’ The man said they were friends. He (the Imam) said, ‘Even if such is the case it is not unlawful.’ The man said, ‘He was doing to him.’ He (the Imam) turned away his face then, while covering his face with his arms, said, ‘Even if it was what it was without doing the hole it is not unlawful to marry but if awqaba (made a hole in him) then marriage is not lawful.’”
