‘A'isha said, “During his private devotional exercises God’s messenger would put his head near me when he was in the mosque, and I would comb it; and he entered the house only to relieve himself.” (Bukhari and Muslim.)
وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا اعْتَكَفَ أَدْنَى إِلَيَّ رَأَسَهِ وَهُوَ فِي الْمَسْجِدِ فَأُرَجِّلُهُ وَكَانَ لَا يَدْخُلُ الْبَيْتَ إِلَّا لحَاجَة الْإِنْسَان "
