فَإِن كُنتَ فِي شَكّٖ مِّمَّآ أَنزَلۡنَآ إِلَيۡكَ فَسۡـَٔلِ ٱلَّذِينَ يَقۡرَءُونَ ٱلۡكِتَٰبَ مِن قَبۡلِكَۚ لَقَدۡ جَآءَكَ ٱلۡحَقُّ مِن رَّبِّكَ فَلَا تَكُونَنَّ مِنَ ٱلۡمُمۡتَرِينَ
Fain kunta fee shakkin mimma anzalnna ilayka faisali allatheena yaqraoona alkitaba min qablika laqad jaaka alhaqqu min rabbika fala takoonanna mina almumtareena
If thou wert in doubt as to what We have revealed unto thee, then ask those who have been reading the Book from before thee: the Truth hath indeed come to thee from thy Lord: so be in no wise of those in doubt.
