It is narrated from Hazrat Saeed bin Musayyib that Hazrat Salman and Hazrat Abdullah bin Salam met each other, and one of them said to his companion: If you meet your Lord (before me), then let me know what I should take with me to meet God. And if I meet God before you, I will come to you and inform you. Then one of them passed away, and he met his companion in a dream and said: Have trust (in Allah) and receive glad tidings, for I have never seen anything like what I have seen. He said this three times.
