Musannaf Ibn Abi Shaybah 28110 — Those who held it recommended

Khalid bin Ar'arah said: I went to a spacious open ground and found about thirty or forty men sitting there, so I sat down with them. Then Sayyiduna Ali (may Allah be pleased with him) came out to us. The narrator said: I did not see him fail to recognise anyone among the people except me. Then he said: "Is there not a man who will ask me, so that he benefits and those sitting with him benefit too?"
