A man said to the Messenger of Allah ﷺ, "Messenger of Allah, tell me something, and keep it brief so that I may grasp it."He said, "Do not become angry."The man repeated his request several times, and each time he replied, "Do not become angry."
أن رجلا قال له: يا رسول الله قل لي قولا وأقلل علي لعلي أعقله قال: لا تغضب فأعاد عليه مرارا كل ذلك يقول: لا تغضب.
Ahmad (15964) and Ibn Hibban (5690) both narrated it from Yahya bin Saeed, from Hisham bin Urwa, from his father, from Ahnaf bin Qays, from Jariya bin Qudama, who mentioned it. Its chain of transmission is sahih, though there was considerable disagreement regarding its chain of transmission, and what I have mentioned is the soundest version of it, as Ibn Hajar indicated in his biographical entry in al-Isabah. There is disagreement as to whether Jariya bin Qudama was a companion, but Abu Hatim and others affirmed that he was, and Ibn Hajar adopted this view in al-Taqrib.
