[Machine] Um Salama, the wife of the Prophet ﷺ, narrated that Subay'a bint Al-Harith gave birth after the death of her husband by about twenty nights or so, and she desired to get married again. Abu As-Sanabil said to her, "You are not allowed to do so until the two prescribed time periods are completed." This was mentioned to the Prophet ﷺ, and he said, "She may get married if she wishes."  

عَنْ أُمِّ سَلَمَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّ سُبَيْعَةَ ابْنَةَ الْحَارِثِ وَضَعَتْ بَعْدَ وَفَاةِ زَوْجِهَا بِعِشْرِينَ لَيْلَةً أَوْ نَحْوِ ذَلِكَ وَأَرَادَتِ التَّزْوِيجَ فَقَالَ لَهَا أَبُو السَّنَابِلِ لَيْسَ لَكِ ذَلِكَ حَتَّى يَأْتِيَ عَلَيْكِ آخِرُ الْأَجَلَيْنِ فَذُكِرَ ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَ تَزَوَّجُ إِذَا شَاءَتْ
