Sayyidah Umm Ma'qil (may Allah be pleased with her) narrates: Abu Ma'qil passed away and left a camel which he had dedicated to the path of Allah. So I came to the Messenger of Allah (peace and blessings be upon him) and said: "O Messenger of Allah, Abu Ma'qil has passed away and left a camel which he had dedicated to the path of Allah, and I have a Hajj due upon me." He (peace and blessings be upon him) said: "O Umm Ma'qil, perform Hajj on your camel, for Hajj is also part of the path of Allah."
