Hadith.2503 - Mu‘awiyah ibn Ammar asked Abu Abdullah (as) about a man who has debt: "Is he obligated to perform Hajj?" Imam (as) replied: "Yes, the Hajj of Islam is obligatory upon those Muslims who can walk. Indeed, most of those who performed Hajj with the Messenger of Allah (swt) (peace of Allah (swt) be upon him and his family) were on foot. The Messenger of Allah (swt) (peace and blessings of Allah (swt) be upon him and his family) passed by Kura‘ al-Ghamim, and the people complained to him about their exhaustion, fatigue, and weakness. Prophet (sw) said: 'Tighten your belts and bind your stomachs.' They did so, and their fatigue and hardship disappeared."
