It is narrated from Yazid bin Umairah that when the time of death approached for Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him), he was told: O Abu Abdur Rahman! At least give us some advice. He said: Make me sit up. Then he said: Knowledge and faith are such things that whoever tries to acquire them from their source and place, he will surely acquire them. He said this three times. Acquire knowledge from four men: Sayyiduna Abu Darda’ Uwaymir, Sayyiduna Salman al-Farsi, Sayyiduna Abdullah bin Mas’ud, and Sayyiduna Abdullah bin Salam—the latter was formerly a Jew, then he accepted Islam. I heard the Messenger of Allah (peace and blessings be upon him) say that he will be among the special ten people who will enter Paradise.
