Sunan Ibn Majah Book 25, Hadith 54
“We were with the Prophet (ﷺ),
and
we were in Ihram. When a rider met us we would lower our garments
from the top of our heads, and when he has gone, we would lift them
up again.”
Another chain reports a similar hadith.
“Who is this?” I said: “I am ‘Abdullah bin Hunain. ‘Abdullah bin ‘Abbas sent me to you to ask you how the Messenger of Allah (ﷺ) used to wash his head when he was in Ihram.” He said: “Abu Ayyub put his hand on the cloth and lowered it until his head appeared, then he said to someone who was pouring water for him, Pour water. So he poured water on his head. Then he rubbed his head with his hands, forwards and backwards, and said: ‘This is what I saw him (ﷺ) doing.’”
“I do not know if it was Asma’ bint Abu Bakr or Su’da bint ‘Awf’ – that the Messenger of Allah (ﷺ) entered upon Duba’ah bint ‘Abdul-Muttalib and said: “What is keeping you, O my aunt, from performing Hajj?” She said: “I am a sick woman, and I am afraid of being prevented (from completing Hajj).” He said: ‘Enter Ihram and stipulate the condition that you will exit Ihram from the point where you are prevented.’”
