It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that a man came to the service of the Prophet (peace and blessings be upon him) and said: "I have a slave girl who serves us and also brings water, and at night I visit her, but I do not like her to become a mother." The Prophet (peace and blessings be upon him) said: "If you wish, you may practice 'azl (withdrawal), otherwise what is destined will surely happen." After some time, the same man came again and said: "That slave girl has become pregnant." The Prophet (peace and blessings be upon him) said: "I had already told you that what is destined will surely happen."
