يونس — Yunus Ayat 94
فَاِنْ كُنْتَ فِيْ شَكٍّ مِّمَّآ اَنْزَلْنَآ اِلَيْكَ فَسْـَٔلِ الَّذِيْنَ يَقْرَءُوْنَ الْكِتٰبَ مِنْ قَبْلِكَ ۚ لَقَدْ جَاۤءَكَ الْحَقُّ مِنْ رَّبِّكَ فَلَا تَكُوْنَنَّ مِنَ الْمُمْتَرِيْنَۙ
Fa in kunta fī syakkim mimmā anzalnā ilaika fas'alil-lażīna yaqra'ūnal-kitāba min qablik(a), laqad jā'akal-ḥaqqu mir rabbika falā takūnanna minal-mumtarīn(a).
"So if you are in doubt, [O Muhammad], about that which We have revealed to you, then ask those who have been reading the Scripture before you. The truth has certainly come to you from your Lord, so never be among the doubters."
