(50) باب التَّمَتُّعِ .
It was narrated that Abu Musa said that:
he used to issue Fatwas concerning Tamattu' Then a man said to him: "Withhold some of your Fatwas ,for you do not know what the commander of the Believers introduced into the rites subsequently." Then when I met him, I asked him. 'Umar said: "I know that the Messenger of Allah and his companions did it, but I did not like that people should lay with their wives in the shade of the Arak trees, and then go out for Hajj with their heads dripping."
