Chapter on Virtues of Hajj
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ اَلْحَجُّ رَاكِباً أَفْضَلُ مِنْهُ مَاشِياً لِأَنَّ رَسُولَ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ حَجَّ رَاكِباً ».
"Hajj performed while riding is better than performing it on foot, because the Messenger of Allah سبحانه وتعالى, peace and blessings be upon him and his family, performed Hajj while riding."
- Ṣaḥīḥ al-Faqīh
