Sayyiduna Jabalah bin Harithah (may Allah be pleased with him) said: I came to the Messenger of Allah (peace and blessings be upon him) and said: "O Messenger of Allah, send my brother Zayd with me." He said: "There he is; if he wishes to go with you, I will not stop him." Sayyiduna Zayd (may Allah be pleased with him) said: "No, by Allah, O Messenger of Allah, I will never prefer anyone over you." The narrator said: So I saw that my brother's opinion was better than mine.
