Hadith 8:1541
Abu Bakr narrated to us, he said: Ma'n ibn 'Isa narrated to us, from Khalid ibn Abi Bakr, he said: I saw Salim sending his young servants for Hajj, and they would not enter into Ihram from Dhu al-Hulayfah; they would enter into Ihram from before that.
حدثنا أبو بكر قال حدثنا معن بن عيسى عن خالد بن أبي بكر قال رأيت سالما يخرج غلمانه إلى الحج فلا يحرمون من ذي الحليفة يحرمون من أمام ذلك
