"Subai'ah Aslamiyyah bint Harith gave birth twenty-odd days after her husband died. When her postnatal bleeding ended, she adorned herself, and was criticized for doing that. Her case was mentioned to the Prophet ﷺ and he said: 'If she does that, then her waiting period is over."'  

وَضَعَتْ سُبَيْعَةُ الأَسْلَمِيَّةُ بِنْتُ الْحَارِثِ حَمْلَهَا بَعْدَ وَفَاةِ زَوْجِهَا بِبِضْعٍ وَعِشْرِينَ لَيْلَةً فَلَمَّا تَعَلَّتْ مِنْ نِفَاسِهَا تَشَوَّفَتْ فَعِيبَ ذَلِكَ عَلَيْهَا وَذُكِرَ أَمْرُهَا لِلنَّبِيِّ ﷺ فَقَالَ إِنْ تَفْعَلْ فَقَدْ مَضَى أَجَلُهَا  

She wrote to them saying that she gave birth twenty-five days after her husband died. Then she prepared herself, seeking to remarry. Abu Sanabil bin Ba'kak passed by her and said: "You are in a hurry; observe waiting period for the longer period, four months and ten days." "So I went to the Prophet ﷺ and said: 'O Messenger of Allah, ﷺ pray for forgiveness for me.' He said: 'Why is that.” I told him (what had happened). He said: 'If you find a righteous husband then marry him."'  

قَدْ أَسْرَعْتِ اعْتَدِّي آخِرَ الأَجَلَيْنِ أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا فَأَتَيْتُ النَّبِيَّ ﷺ فَقُلْتُ يَا رَسُولَ اللَّهِ اسْتَغْفِرْ لِي قَالَ وَمِمَّ ذَاكَ فَأَخْبَرْتُهُ فَقَالَ إِنْ وَجَدْتِ زَوْجًا صَالِحًا فَتَزَوَّجِي  

the Prophet ﷺ told Subai'ah to get married, when her postnatal bleeding ended.  

أَنَّ النَّبِيَّ ﷺ أَمَرَ سُبَيْعَةَ أَنْ تَنْكِحَ إِذَا تَعَلَّتْ مِنْ نِفَاسِهَا  

"By Allah, for those who would like to go through the process of praying for Allah's curse to be upon the one who is wrong, the shorter Surah concerning women[l] was revealed after (the Verses[2] which speak of the waiting period of) four months and ten (days)." [1] (65:40), [2] (2:234)  

وَاللَّهِ لَمَنْ شَاءَ لاَعَنَّاهُ لأُنْزِلَتْ سُورَةُ النِّسَاءِ الْقُصْرَى بَعْدَ أَرْبَعَةِ أَشْهُرٍ وَعَشْرًا
