The word(s) "trieth" appears 3 time(s) in 3 verse(s) in Quran in Muhammad Pickthal translation.

(1) And be not like unto her who unravelleth the thread, after she hath made it strong, to thin filaments, making your oaths a deceit between you because of a nation being more numerous than (another) nation. Allah only trieth you thereby, and He verily will explain to you on the Day of Resurrection that wherein ye differed.
