The word(s) "silent" appears 4 time(s) in 4 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Say: "Who is it that delivereth you from the dark recesses of land and sea, when ye call upon Him in humility and silent terror: 'If He only delivers us from these (dangers), (we vow) we shall truly show our gratitude'?"

(2) And he turned away from them, and said: "How great is my grief for Joseph!" And his eyes became white with sorrow, and he fell into silent melancholy.

(3) And that cry of theirs ceased not, till We made them as a field that is mown, as ashes silent and quenched.

(4) It was no more than a single mighty Blast, and behold! they were (like ashes) quenched and silent.
