Hadith 8:904
Abu Bakr narrated to us, he said: Hafs narrated to us, from Mujalid, from al-Sha’bi, who said: If he says, "If I do such and such, then I am in the state of ihram for Hajj," he said: He performs Hajj with the people.
حدثنا أبو بكر قال حدثنا حفص عن مجالد عن الشعبي قال إذا قال إن فعلت كذا وكذا فأنا محرم بحجة قال يحج مع الناس
