It is narrated from Hazrat Abu Sanabil (may Allah be pleased with him) that Sabi'ah gave birth to a child only 23 or 25 days after the death of her husband, and she began to prepare for another marriage. Someone came to the Prophet Muhammad (peace and blessings be upon him) and informed him of this. The Prophet Muhammad (peace and blessings be upon him) said, "If she does so, (it is fine because) her waiting period ('iddah) has ended."
