Jami` at-Tirmidhi, Volume 6, Book 46, Hadith 3804 (DarusSalam) ⓘ
Narrated Yazid bin 'Umairah: "When death was upon Mu'adh bin Jabal, it was said to him: 'O Abu 'Abdur-Rahman, advise us.' He said: 'Sit me up.' So he said: 'Indeed, knowledge and faith are at their place, whoever desires them shall find them.' He said that three times. 'And seek knowledge from four men: 'Uwaimir Abu Ad-Darda, with Salman Al-Farisi, with 'Abdullah bin Mas'ud, and with 'Abdullah bin Salam who used to be a Jew and then accepted Islam. For indeed, I heard the Messenger of Allah saying, "Indeed he is the tenth of ten in Paradise."
