Yazid bin Umairah narrates: When the last moments of Sayyiduna Mu'adh bin Jabal رضي الله عنه approached, people said: O Abu Abdur Rahman, advise us. He said: Make me sit up, then he said: The source of action and faith is the same, whoever seeks both of them will attain both. Knowledge and faith have a specific place, whoever seeks both of them will attain both. Seek knowledge from four men: Abu Darda, Salman al-Farsi, Abdullah bin Mas'ud, and Abdullah bin Salam, who was formerly a Jew and then became a Muslim. I heard the Prophet صلى الله عليه وسلم say this: "He is the tenth among those ten men who are destined for Paradise."
