Respected استاد, in Usul al-Kafi, Imam Ja‘far al-Sadiq was performing the obligatory circumambulation with one of his companions when someone called out to the companion. Because they were performing the obligatory circumambulation, and because he was accompanying the Imam, the companion did not answer. The Imam noticed and asked him about the person. When he learned that the man was a Muslim, he said, “Why didn’t you answer him?” The companion replied that they were performing the obligatory circumambulation and that he had not wanted to leave the Imam or show him disrespect. The Imam told him to go and attend to the man’s need, and to give him half his wealth. In light of this, should believers go to such lengths to meet one another’s needs—as though a person were doing a kindness to himself?
Please explain the obligatory rights believers owe one another and are bound to observe. If we fall short, will we be questioned about it in God’s presence?
