The word(s) "signs" appears 342 time(s) in 321 verse(s) in Quran in Abdullah Yusuf Ali translation.

(181) Being true in faith to Allah, and never assigning partners to Him: if anyone assigns partners to Allah, is as if he had fallen from heaven and been snatched up by birds, or the wind had swooped (like a bird on its prey) and thrown him into a far-distant place.

(189) "My signs used to be rehearsed to you, but ye used to turn back on your heels-

(190) "Were not My signs rehearsed to you, and ye did but treat them as falsehood?"
