يُخْرِجُ إِلَىَّ رَأْسَهُ مِنَ الْمَسْجِدِ وَهُوَ مُجَاوِرٌ فَأَغْسِلُهُ وَأَنَا حَائِضٌ .
It was narrated that 'Aishah said: "The Prophet (ﷺ) would put his head out for me while he was performing I'tikaf [1] and I would wash it, when I was menstruating." [1] Mujawir ("next door") here means while performing I'tikaf.
