It is narrated from Hazrat Abu Saeed Khudri (may Allah be pleased with him) that once he was sitting with the Prophet (peace and blessings be upon him) when an Ansari man came and said, "O Messenger of Allah (peace and blessings be upon him)! We have obtained captives, and we wish to release them for ransom, so what is your opinion regarding 'azl (withdrawal)?" The Prophet (peace and blessings be upon him) said, "Do you do that? If you do not do so, it will not make any difference, because the soul whom Allah has decided to bring into existence will surely come into existence."
