The saying of Allah, the Mighty and Majestic: "And Hajj to the House is a duty owed to Allah by people, for whoever is able to find a way to it." [Surah Al Imran: 97]
And it has been narrated to us from the Prophet (peace and blessings be upon him) that: "The 'way' (ability) means provisions and a mount."
Muhammad bin Abbad al-Makhzumi narrates from Sayyiduna Ibn Umar (may Allah be pleased with them both) that he heard the Prophet (peace and blessings be upon him) (say about): "Whoever is able to find a way to it" [Surah Al Imran: 97], he said: "Provisions and a mount."
We have narrated it through authentic routes from al-Hasan al-Basri from the Prophet (peace and blessings be upon him) as mursal, and that gives strength to this musnad report.
