It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that Sabi'ah bint Harith gave birth to a child only fifteen days after the death of her husband. During this period, Abu Sanabil came to her and said, "It seems as if you want to remarry? It is not permissible for you to remarry until you have completed the long waiting period ('iddah)." Sabi'ah went to the Prophet (peace and blessings be upon him) and informed him of what Abu Sanabil had said. The Prophet (peace and blessings be upon him) said: "Abu Sanabil has made a mistake. If a proposal comes to you that you like, then come and inform me." And the Prophet (peace and blessings be upon him) informed her that her 'iddah had been completed.
