وَعَنْ أُمِّ سَلَمَةَ رَضِيَ اَللَّهُ عَنْهَا قَالَتْ: { كَانَتِ اَلنُّفَسَاءُ تَقْعُدُ فِي عَهْدِ رَسُولِ اَللَّهِ - صلى الله عليه وسلم -بَعْدَ نِفَاسِهَا أَرْبَعِينَ } رَوَاهُ اَلْخَمْسَةُ إِلَّا النَّسَائِيَّ, وَاللَّفْظُ لِأَبِي دَاوُد َ [1] .
Narrated Umm Salamah (RAA): During the lifetime of the Prophet (Peace be upon him) the women having bleeding after delivery (postnatal or puerperal blood) would refrain (from prayer) for forty days. [Reported by Al-Khamsa except An-Nasa’i, and the version is that of Abu Da’ud].
