Surah Yunus Verse 94 - English Translation by Muhammad Mahmoud Ghali
Surah Yunusفَإِن كُنتَ فِي شَكّٖ مِّمَّآ أَنزَلۡنَآ إِلَيۡكَ فَسۡـَٔلِ ٱلَّذِينَ يَقۡرَءُونَ ٱلۡكِتَٰبَ مِن قَبۡلِكَۚ لَقَدۡ جَآءَكَ ٱلۡحَقُّ مِن رَّبِّكَ فَلَا تَكُونَنَّ مِنَ ٱلۡمُمۡتَرِينَ
So, in case you are in doubt regarding what We have sent down to you, then ask the ones who read the Book even before you. Indeed the Truth has already come to you from your Lord, so do not definitely be of the constant wranglers
