Sunan an-Nasa'i, Book 27, Hadith 120 (In-Book) ⓘ

It was narrated that Abu As-Sanabil said: "Subai'ah gave birth twenty-three or twenty-five days after her husband died, and when her Nifas ended she expressed her wish to remarry and was criticized for that. Mention of that was made to the Messenger of Allah and he said: 'There is nothing to stop her; her term has ended.'"

أَخْبَرَنِي مُحَمَّدُ بْنُ قُدَامَةَ، قَالَ أَخْبَرَنِي جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ أَبِي السَّنَابِلِ، قَالَ وَضَعَتْ سُبَيْعَةُ حَمْلَهَا بَعْدَ وَفَاةِ زَوْجِهَا بِثَلاَثَةٍ وَعِشْرِينَ أَوْ خَمْسَةٍ وَعِشْرِينَ لَيْلَةً فَلَمَّا تَعَلَّتْ تَشَوَّفَتْ لِلأَزْوَاجِ فَعِيبَ ذَلِكَ عَلَيْهَا فَذُكِرَ ذَلِكَ لِرَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ ‏ "‏ مَا يَمْنَعُهَا قَدِ انْقَضَى أَجَلُهَا ‏" ‏ ‏.‏
