The word(s) "silent" appears 4 time(s) in 4 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And if you invite them to guidance, they will not follow you; it is the same to you whether you invite them or you are silent.

(2) And when the Quran is recited, then listen to it and remain silent, that mercy may be shown to you.

(3) Say: Call upon Allah or call upon, the Beneficent Allah; whichever you call upon, He has the best names; and do not utter your prayer with a very raised voice nor be silent with regard to it, and seek a way between these.

(4) And when We turned towards you a party of the jinn who listened to the Quran; so when they came to it, they said: Be silent; then when it was finished, they turned back to their people warning (them).
