What is this that I see you embellished; perhaps you are inclined to marry, By Allah, you cannot marry unless four months and ten days (of 'Idda are passed). When he said that. I dressed myself, and as it was evening I came to Messenger of Allah ﷺ and asked him about it, and he gave me a religious verdict that I was allowed to marry when I had given birth to a child and asked me to marry if I so liked. Ibn Shihab said: I do not find any harm fur her in marrying when she has given birth to a child even when she is bleeding (after the birth of the child) except that her husband should not go near her until she is purified.  

أَنْ يَدْخُلَ عَلَى سُبَيْعَةَ بِنْتِ الْحَارِثِ الأَسْلَمِيَّةِ فَيَسْأَلَهَا عَنْ حَدِيثِهَا وَعَمَّا قَالَ لَهَا رَسُولُ اللَّهِ ﷺ حِينَ اسْتَفْتَتْهُ فَكَتَبَ عُمَرُ بْنُ عَبْدِ اللَّهِ إِلَى عَبْدِ اللَّهِ بْنِ عُتْبَةَ يُخْبِرُهُ أَنَّ سُبَيْعَةَ أَخْبَرَتْهُ أَنَّهَا كَانَتْ تَحْتَ سَعْدِ ابْنِ خَوْلَةَ وَهُوَ فِي بَنِي عَامِرِ بْنِ لُؤَىٍّ وَكَانَ مِمَّنْ شَهِدَ بَدْرًا فَتُوُفِّيَ عَنْهَا فِي حَجَّةِ الْوَدَاعِ وَهْىَ حَامِلٌ فَلَمْ تَنْشَبْ أَنْ وَضَعَتْ حَمْلَهَا بَعْدَ وَفَاتِهِ فَلَمَّا تَعَلَّتْ مِنْ نِفَاسِهَا تَجَمَّلَتْ لِلْخُطَّابِ فَدَخَلَ عَلَيْهَا أَبُو السَّنَابِلِ بْنُ بَعْكَكٍ رَجُلٌ مِنْ بَنِي عَبْدِ الدَّارِ فَقَالَ لَهَا مَا لِي أَرَاكِ مُتَجَمِّلَةً لَعَلَّكِ تَرْجِينَ النِّكَاحَ إِنَّكِ وَاللَّهِ مَا أَنْتِ بِنَاكِحٍ حَتَّى تَمُرَّ عَلَيْكِ أَرْبَعَةُ أَشْهُرٍ وَعَشْرٌ قَالَتْ سُبَيْعَةُ فَلَمَّا قَالَ لِي ذَلِكَ جَمَعْتُ عَلَىَّ ثِيَابِي حِينَ أَمْسَيْتُ فَأَتَيْتُ رَسُولَ اللَّهِ ﷺ فَسَأَلْتُهُ عَنْ ذَلِكَ فَأَفْتَانِي بِأَنِّي قَدْ حَلَلْتُ حِينَ وَضَعْتُ حَمْلِي وَأَمَرَنِي بِالتَّزَوُّجِ إِنْ بَدَا لِي قَالَ ابْنُ شِهَابٍ فَلاَ أَرَى بَأْسًا أَنْ تَتَزَوَّجَ حِينَ وَضَعَتْ وَإِنْ كَانَتْ فِي دَمِهَا غَيْرَ أَنْ لاَ يَقْرَبُهَا زَوْجُهَا حَتَّى تَطْهُرَ  

Her 'Idda is that period which is longer of the two (between four months and ten days and the birth of the child, whichever is longer). AbuSalama, however said: Her period of 'Idda is over (with the birth of the child), and they were contending with each other over this issue, whereupon Abu Huraira (Allah be pleased with him) said: I subscribe (to the view) held by my nephew (i. e. Abu Salama). They sent Kuraib (the freed slave of Ibn 'Abbas) to Umm Salama to ask her about it. He came (back) to them and informed them that Umm Salama (Allah be pleased with her) said that Subai'ah al-Aslamiyya gave birth to a child after the death of her husband when the few flights (had hardly) passed and she made mention of that to Messenger of Allah ﷺ and he commanded her to marry.  

وَقَالَ أَبُو سَلَمَةَ قَدْ حَلَّتْ فَجَعَلاَ يَتَنَازَعَانِ ذَلِكَ قَالَ فَقَالَ أَبُو هُرَيْرَةَ أَنَا مَعَ ابْنِ أَخِي يَعْنِي أَبَا سَلَمَةَ فَبَعَثُوا كُرَيْبًا مَوْلَى ابْنِ عَبَّاسٍ إِلَى أُمِّ سَلَمَةَ يَسْأَلُهَا عَنْ ذَلِكَ فَجَاءَهُمْ فَأَخْبَرَهُمْ أَنَّ أُمَّ سَلَمَةَ قَالَتْ إِنَّ سُبَيْعَةَ الأَسْلَمِيَّةَ نُفِسَتْ بَعْدَ وَفَاةِ زَوْجِهَا بِلَيَالٍ وَإِنَّهَا ذَكَرَتْ ذَلِكَ لِرَسُولِ اللَّهِ ﷺ فَأَمَرَهَا أَنْ تَتَزَوَّجَ  

They sent him to Umm Salama, but no mention was made of Kuraib.  

أَنَّقَالَ فِي حَدِيثِهِ فَأَرْسَلُوا إِلَى أُمِّ سَلَمَةَ وَلَمْ يُسَمِّ كُرَيْبًا
