Yahya related to me from Malik fromAbdullah ibn Abi Bakr that a
mawla of Amir bint Abd ar-Rahman called Ruqayya told him that she once
set out with Amra bint Abd ar-Rahman to go to Makka. She said, ''Amra
entered Makka on the eighth of Dhu'l-Hijja, and I was with her. She
did tawaf of the House, and say between Safa and Marwa, and then
entered the back of the mosque. She asked me, 'Do you have a pair of
scissors with you?' and I said, 'No.' She said, 'Then try and find
some for me.' I went and looked for some and brought them back and she
cut some hair from the tresses of her head.Then, on the day of
sacrifice, she slaughtered a sheep."
Muwatta Malik Book 20, Hadith 173
Once the Prophet (ﷺ) was riding his camel and a man was holding its rein. The Prophet (ﷺ) asked, "What is
the day today?" We kept quiet, thinking that he might give that day another name. He said, "Isn't it the
day of Nahr (slaughtering of the animals of sacrifice)" We replied, "Yes." He further asked, "Which
month is this?" We again kept quiet, thinking that he might give it another name. Then he said, "Isn't it
the month of Dhul-Hijja?" We replied, "Yes." He said, "Verily! Your blood, property and honor are
sacred to one another (i.e. Muslims) like the sanctity of this day of yours, in this month of yours and in
this city of yours. It is incumbent upon those who are present to inform those who are absent because
those who are absent might comprehend (what I have said) better than the present audience."
Sahih al-Bukhari Book 3, Hadith 9
