Silah bin Ashyam narrates: "Abu Rifa'ah (may Allah be pleased with him) was martyred while we were on a military expedition. Then I saw in a dream as though I were seeing Abu Rifa'ah on a swift she-camel while I was on a slow camel, following behind him. He would turn her aside until I would say: Now I will make him hear my voice; then he would let her go and she would speed off, and I would keep following him. I interpreted my dream to mean that this is the path of Abu Rifa'ah which I take, and that after him I strive hard in good deeds."
