Mukhtasar Muslim

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him), he states that a man asked the Noble Prophet (peace and blessings be upon him), "I have a slave woman with whom I practice coitus interruptus (withdrawal)." The Messenger of Allah (peace and blessings be upon him) said, "If Allah intends to create someone, this (withdrawal) cannot prevent it." (A few days later) that man came to the Prophet (peace and blessings be upon him) and said, "The slave woman I mentioned to you has become pregnant." The Prophet (peace and blessings be upon him) said, "I am the servant of Allah and His Messenger."
