Muwatta Imam Malik Book of Shortening the Prayer, Hadith 31

Yahya related to me from Malik from Abu'n Nadr, the mawla of Umar ibn Ubaydullah, that Abu Murra, the mawla of Aqeel ibn Abi Talib, told him that he had heard Umm Hani bint Abi Talib say, "I went to the Messenger of Allah ﷺ in the year of the conquest and found him doing ghusl while his daughter Fatima, was screening him with a garment. I said to him, 'Peace be upon you' and he said, 'Who is that?' I replied, 'Umm Hani bint Abi Talib,' and he said, 'Welcome, Umm Hani!' When he had finished his ghusl, he stood and prayed eight rakas, covering himself with one garment, and then came away. I said, 'Messenger of Allah, the son of my mother, AIi, says that he is determined to kill so-and-so, son of Hubayra, a man I have placed under my protection.' The Messenger of Allah ﷺ said, 'We give protection to whoever you have given protection to, Umm Hani.' "
Umm Hani related that this incident happened in the morning.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي النَّضْرِ، مَوْلَى عُمَرَ بْنِ عُبَيْدِ اللَّهِ أَنَّ أَبَا مُرَّةَ، مَوْلَى عَقِيلِ بْنِ أَبِي طَالِبٍ أَخْبَرَهُ أَنَّهُ، سَمِعَ أُمَّ هَانِئٍ بِنْتَ أَبِي طَالِبٍ، تَقُولُ ذَهَبْتُ إِلَى رَسُولِ اللَّهِ ﷺ عَامَ الْفَتْحِ فَوَجَدْتُهُ يَغْتَسِلُ وَفَاطِمَةُ ابْنَتُهُ تَسْتُرُهُ بِثَوْبٍ - قَالَتْ - فَسَلَّمْتُ عَلَيْهِ فَقَالَ " مَنْ هَذِهِ " . فَقُلْتُ أُمُّ هَانِئٍ بِنْتُ أَبِي طَالِبٍ . فَقَالَ " مَرْحَبًا بِأُمِّ هَانِئٍ " . فَلَمَّا فَرَغَ مِنْ غُسْلِهِ قَامَ فَصَلَّى ثَمَانِيَ رَكَعَاتٍ مُلْتَحِفًا فِي ثَوْبٍ وَاحِدٍ ثُمَّ انْصَرَفَ فَقُلْتُ يَا رَسُولَ اللَّهِ زَعَمَ ابْنُ أُمِّي عَلِيٌّ أَنَّهُ قَاتِلٌ رَجُلاً أَجَرْتُهُ فُلاَنُ بْنُ هُبَيْرَةَ . فَقَالَ رَسُولُ اللَّهِ ﷺ " قَدْ أَجَرْنَا مَنْ أَجَرْتِ يَا أُمَّ هَانِئٍ " . قَالَتْ أُمُّ هَانِئٍ وَذَلِكَ ضُحًى .
