فَإِن So if كُنتَ you are فِى in شَكٍّۢ doubt مِّمَّآ of what أَنزَلْنَآ We have revealed إِلَيْكَ to you فَسْـَٔلِ then ask ٱلَّذِينَ those who يَقْرَءُونَ (have been) reading ٱلْكِتَـٰبَ the Book مِن before you قَبْلِكَ ۚ before you لَقَدْ Verily جَآءَكَ has come to you ٱلْحَقُّ the truth مِن from رَّبِّكَ your Lord فَلَا so (do) not تَكُونَنَّ be مِنَ among ٱلْمُمْتَرِينَ the doubters ٩٤
So if you are in doubt, [O Muḥammad], 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.
