Muwatta Imam Malik Book of I'tikaf in Ramadan, Hadith 1

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 ﷺ said,"When the Messenger of Allah ﷺ 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 ﷺ أَنَّهَا قَالَتْ كَانَ رَسُولُ اللَّهِ ﷺ إِذَا اعْتَكَفَ يُدْنِي إِلَىَّ رَأْسَهُ فَأُرَجِّلُهُ وَكَانَ لاَ يَدْخُلُ الْبَيْتَ إِلاَّ لِحَاجَةِ الإِنْسَانِ .
