The word(s) "sign" appears 351 time(s) in 320 verse(s) in Quran in Mohsin Khan translation.

(151) "They are those who deny the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord and the Meeting with Him (in the Hereafter). So their works are in vain, and on the Day of Resurrection, We shall assign no weight for them.

(152) "That shall be their recompense, Hell; because they disbelieved and took My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and My Messengers by way of jest and mockery.

(153) [Zakariyya (Zachariah)] said: "My Lord! Appoint for me a sign." He said: "Your sign is that you shall not speak unto mankind for three nights, though having no bodily defect."

(154) Then he came out to his people from Al-Mihrab (a praying place or a private room), and he told them by signs to glorify Allah's Praises in the morning and in the afternoon.

(155) He said: "So (it will be), your Lord said: 'That is easy for Me (Allah): And (We wish) to appoint him as a sign to mankind and a mercy from Us (Allah), and it is a matter (already) decreed, (by Allah).' "

(156) "And press your (right) hand to your (left) side: it will come forth white (and shining), without any disease as another sign,

(157) "That We may show you (some) of Our Greater signs.

(158) "Go you and your brother with My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and do not, you both, slacken and become weak in My Remembrance.

(159) "So go you both to him, and say: 'Verily, we are Messengers of your Lord, so let the Children of Israel go with us, and torment them not; indeed, we have come with a sign from your Lord! And peace will be upon him who follows the guidance!

(160) Eat and pasture your cattle (therein); verily, in this are Ayat (proofs and signs) for men of understanding.
