Musannaf Ibn Abi Shaybah 27433 — A man saying to another: May Allah

Muhammad bin Suqah said: Maymun bin Mihran came to us, and a man said to him: 'Hayyaka Allah' (May Allah keep you alive). He said: "Do not say it like that. This is the greeting of young men. Rather say: 'Hayyakumu Allahu bi-s-salam' (May Allah keep you alive with peace)."
