فَاِنْ كُنْتَ فٖی شَكٍّ مِمَّٓا اَنْزَلْنَٓا اِلَیْكَ فَسْـَٔلِ الَّذٖینَ یَقْرَؤُ𐻿نَ الْكِتَابَ مِنْ قَبْلِكَۚ لَقَدْ جَٓاءَكَ الْحَقُّ مِنْ رَبِّكَ فَلَا تَكُونَنَّ مِنَ الْمُمْتَرٖینَۙ
Fain kunta fee shakkin mimma anzalnna ilayka faisali allatheena yaqraoona alkitaba min qablika laqad jaaka alhaqqu min rabbika fala takoonanna mina almumtareena

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
Saheeh International
And if thou (Muhammad) art in doubt concerning that which We reveal unto thee, then question those who read the Scripture (that was) before thee. Verily the Truth from thy Lord hath come unto thee. So be not thou of the waverers
