Muwatta Imam Malik Book of Prayer in Ramadan, Hadith 8
Yahya related to me from Malik from Hisham ibn Urwa from his father that Dhakwan Abu Amr (a slave belonging to A'isha, the wife of the Prophet ﷺ who was freed by her after her death) used to stand in prayer and recite for her in Ramadan.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، أَنَّ ذَكْوَانَ أَبَا عَمْرٍو، - وَكَانَ عَبْدًا لِعَائِشَةَ زَوْجِ النَّبِيِّ ﷺ فَأَعْتَقَتْهُ عَنْ دُبُرٍ مِنْهَا - كَانَ يَقُومُ يَقْرَأُ لَهَا فِي رَمَضَانَ .
