10:94
فَإِن كُنتَ فِی شَكࣲّ مِّمَّاۤ أَنزَلۡنَاۤ إِلَیۡكَ فَسۡـَٔلِ ٱلَّذِینَ یَقۡرَءُونَ ٱلۡكِتَـٰبَ مِن قَبۡلِكَۚ لَقَدۡ جَاۤءَكَ ٱلۡحَقُّ مِن رَّبِّكَ فَلَا تَكُونَنَّ مِنَ ٱلۡمُمۡتَرِینَ
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.
— Mohammed Marmaduke William Pickthall
