Yahya related to me from Malik from Abdullah ibn Abi Bakr that Asma bint Umays washed Abu Bakr as-Siddiq when he died. Then she went out and asked some of the muhajirun who were there, "I am fasting and this is an extremely cold day. Do I have to do ghusl?" They said, "No."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرٍ، أَنَّ أَسْمَاءَ بِنْتَ عُمَيْسٍ، غَسَّلَتْ أَبَا بَكْرٍ الصِّدِّيقَ حِينَ تُوُفِّيَ ثُمَّ خَرَجَتْ فَسَأَلَتْ مَنْ حَضَرَهَا مِنَ الْمُهَاجِرِينَ فَقَالَتْ إِنِّي صَائِمَةٌ وَإِنَّ هَذَا يَوْمٌ شَدِيدُ الْبَرْدِ فَهَلْ عَلَىَّ مِنْ غُسْلٍ فَقَالُوا لاَ .
