Musannaf Ibn Abi Shaybah 37776 — The reward of glorifying and praising

It is narrated from Ka'b that he said: Among the best of deeds is subhat al-hadith, and among the worst of deeds is tajdif. The narrator said: I submitted: "O Abu Abd al-Rahman, what is subhat al-hadith?" He (may Allah have mercy on him) said: "That a man glorifies Allah while the other people are talking." The narrator said: I submitted: "What is tajdif?" He (may Allah have mercy on him) said: "That people are doing well, but when they are asked (about their state) they say: 'Badly.'"
