Abdullah bin Harith says that once during the caliphate of Umar or the caliphate of Uthman, I had the honor of performing Umrah with Sayyiduna Ali (may Allah be pleased with him). During this time, he stayed at the house of his sister, Sayyida Umm Hani (may Allah be pleased with her). When he finished the Umrah, he returned to her house. Water was arranged for his bath, and he performed ghusl. He had just finished bathing when a delegation from Iraq arrived. They said, "O Abu al-Hasan! We have come to you with a question. We wish that you tell us something about it." Sayyiduna Ali (may Allah be pleased with him) said, "I think that Sayyiduna Mughirah bin Shu'bah (may Allah be pleased with him) has narrated to you this hadith that he was the last one to be with the Prophet (peace and blessings be upon him)." They said, "Exactly, we have come to ask you about this." He said, "The one who was the last with the Prophet (peace and blessings be upon him) was Qutham bin Abbas."
