Chapter: The stay of the emigrants in Makkah after Hajj
Narrated `Abdur-Rahman bin Humaid Az-Zuhri:
I heard `Umar bin `Abdul-Aziz asking As-Sa'ib, the nephew of An-Nimr. "What have you heard about residing in Mecca?" The other said, "I heard Al-Ala bin Al-Hadrami saying, Allah's Messenger (ﷺ) said: An Emigrant is allowed to stay in Mecca for three days after departing from Mina (i.e. after performing all the ceremonies of Hajj)"
