It was narrated from Al-Miswar bin Makhramah that Subai'ah Al-Aslamiyyah gave birth one day after her husband died. She came to the Messenger of Allah and asked his permission to marry, and he gave her permission to marry and she married.
أَنَّ سُبَيْعَةَ الأَسْلَمِيَّةَ نُفِسَتْ بَعْدَ وَفَاةِ زَوْجِهَا بِلَيَالٍ فَجَاءَتْ رَسُولَ اللَّهِ ﷺ فَاسْتَأْذَنَتْ أَنْ تَنْكِحَ فَأَذِنَ لَهَا فَنَكَحَتْ
