The Mother of the Believers, Sayyidah Aishah Siddiqah (may Allah be pleased with her), says: The Messenger of Allah (peace and blessings be upon him) was asked about "the way to Hajj" (al-sabil ila al-hajj), and he (peace and blessings be upon him) said: "Provision for the journey and a mount."
Other hadiths have been narrated on this, none of which is authentic. The hadith of Ibrahim bin Yazid is the best known of them, and we have supported it with what al-Hasan al-Basri narrated, even though it is munqati' (with a broken chain).
