The son of Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) narrates: I heard Sayyiduna Ali ibn Abi Talib (may Allah be pleased with him) send Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) for a certain task and instructed him regarding something about that task. Sayyiduna Ali (may Allah be pleased with him) said to him: The Noble Prophet (peace and blessings of Allah be upon him) said to me: "O Ali (may Allah be pleased with him)! Ask Allah Almighty for guidance and steadfastness. By guidance, I mean guidance to the path, and by the straight path, I mean that you set your arrow straight." Sayyiduna Ali (may Allah be pleased with him) also mentioned: The Noble Prophet (peace and blessings of Allah be upon him) forbade me from using qassi and red mithrah (types of silk garments), and also forbade me from wearing a ring on this and this finger when taking water. Sayyiduna Ali ibn Abi Talib (may Allah be pleased with him) indicated towards the index finger and the middle finger while saying this.

Imam Humaydi (may Allah have mercy on him) says: Sufyan narrates this narration from the narrator 'Asim, from Abu Bakr, the son of Sayyiduna Abu Musa (may Allah be pleased with him), so it was said to him: Other hadith scholars have narrated this narration from Abu Burdah, the son of Sayyiduna Abu Musa (may Allah be pleased with him). So he said: I have memorized this narration in this way, that it is narrated from Abu Bakr ibn Abu Musa. But if others narrate differently from me, you may include these words: that this narration is from one of the sons of Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him). So it was Sufyan's practice that after this, sometimes he would narrate this narration as being from the son of Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him), and sometimes he would forget, so according to what he had heard, he would narrate it from Abu Bakr, the son of Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him).
