Musannaf Ibn Abi Shaybah 37383 — The words of Salman

It is narrated from Sa'id bin al-Musayyib that Sayyiduna Salman and Sayyiduna Abdullah bin Salam (may Allah be pleased with them both) met each other, and one of them said to his companion: "If you meet your Lord (before me), tell me what you encountered from Allah. And if I meet Allah before you, I will meet you and tell you." Then one of them died, and he met his companion in a dream and said: "Put your trust in Allah and receive glad tidings, for I have seen nothing at all like trust in Allah." He said this three times.
