575 — Muhammad ibn Umar ibn Muhammad ibn Humayd informed us. He said: Muhammad ibn Makhlad narrated to us. He said: Muhammad ibn Isma'il al-Hassani narrated to us. He said: Waki' narrated to us. He said: al-A'mash narrated to us, from Ibrahim, from Abd al-Rahman ibn Yazid, who said: We were with Salman when he went out to relieve himself. He then returned, and I said, “O Abu Abd Allah, if only you would perform ablution, perhaps we could ask you about some verses.” He said, “I am not going to touch it, for none touch it except the purified.” Then he recited to us whatever we wished.
