Muwatta Malik, Book 19, Hadith 693 (In-Book) ⓘ

Yahya related to me from Malik from Ibn Shihab from Urwa ibn az- Zubayr from Amra bint Abd ar-Rahman that A'isha, the wife of the Prophet, may Allah bless him and grant him peace, said,"When the Messenger of Allah, may Allah bless him and grant him peace, did itikaf he would bring his head near to me and I would comb it. He would only go into the house to relieve himself."

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، عَنْ عَمْرَةَ بِنْتِ عَبْدِ الرَّحْمَنِ، عَنْ عَائِشَةَ، زَوْجِ النَّبِيِّ صلى الله عليه وسلم أَنَّهَا قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا اعْتَكَفَ يُدْنِي إِلَىَّ رَأْسَهُ فَأُرَجِّلُهُ وَكَانَ لاَ يَدْخُلُ الْبَيْتَ إِلاَّ لِحَاجَةِ الإِنْسَانِ ‏.‏
