40 Hadith Qudsi, Chapter: 40 Hadith Qudsi

who said that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Let not any one of you belittle himself." They said: "O Messenger of Allah, how can any one of us belittle himself?" He said: "He finds a matter concerning Allah about which he should say something, and he does not say [it], so Allah (mighty and sublime be He) says to him on the Day of Resurrection: 'What prevented you from saying something about such-and-such and such-and-such?' He will say: 'It was] out of fear of people.' Then He says: 'Rather it is I whom you should more properly fear.' " It was related by Ibn Majah with a sound chain of authorities.
