Imam Ali (a) was bowing during his prayer at that time. He pointed his little finger, on which was a ring, towards the beggar who came forward and took away the ring. The incident occurred in the Prophet's presence, and he raised his face towards heaven and prayed: "O Lord! my brother Musa had begged of Thee to open his breast and to make his work easy for him, to loosen the knot of his tongue so that people might understand him, and to appoint from among his relations his brother, as his wali, and to strengthen his back with Harun and to make Harun his partner in his work.
