When does the waiting period (iddah) for a woman whose husband died on January 5, 2007, end? Is it permissible for her to leave her home before the waiting period concludes? Is a ritual bath (ghusl) required after the waiting period ends, and how is this bath performed?

If a woman is pregnant, her iddah (waiting period) ends upon delivery. If she is not pregnant, and her husband passed away on Dhu al-Hijjah 15, 1427 AH (corresponding to January 5, 2007), she calculates the remaining days of Dhu al-Hijjah (14 or 15 days, depending on the completeness of the month), then adds three full months (Muharram, Safar, Rabi' al-Awwal), then completes 30 days from Rabi' al-Thani (15 or 16 days) to make a full four months, then adds another ten days until the same time of death.

Consequently, her iddah ends on Rabi' al-Thani 25, 1428 AH (corresponding to May 12, 2007) if Dhu al-Hijjah was complete, or on Rabi' al-Thani 24, 1428 AH (corresponding to May 11, 2007) if Dhu al-Hijjah was incomplete, at the same hour her husband passed away. She is not required to perform ghusl (ritual bath) at the end of her iddah if she is in a state of purity.
