Explanation & Benefits
Hafiz Muhammad Ameen
(1) The ruling mentioned in this surah (Surah at-Talaq) will specify the ruling of Surah al-Baqarah. Consequently, the waiting period (‘iddah) of a pregnant woman whose husband has passed away is until childbirth, that is, the birth of the child.
(2) The repetition of this hadith to such an extent is to show the difference in the chain of narration; furthermore, through this, all the details of the incident become apparent.
