فَإِن كُنتَ فِي شَكٍّ مِّمَّا أَنزَلْنَا إِلَيْكَ فَاسْأَلِ الَّذِينَ يَقْرَءُونَ الْكِتَابَ مِن قَبْلِكَ لَقَدْ جَاءَكَ الْحَقُّ مِن رَّبِّكَ فَلَا تَكُونَنَّ مِنَ الْمُمْتَرِينَ
Fa-in kunta fee shakkin mimma anzalnna ilayka fais-ali allatheena yaqraoona alkitaba min qablika laqad jaaka alhaqqu min rabbika fala takoonanna mina almumtareena
So if you are in doubt of what We have revealed to you, then ask those who (have been) reading the Book before you. Verily, has come to you the truth from your Lord, so (do) not be among the doubters.
AND SO, [O man,] if thou art in doubt about [the truth of] what We have [now] bestowed upon thee from on high, ask those who read the divine writ [revealed] before thy time: [and thou wilt find that,] surely, the truth has now come unto thee from thy Sustainer. Be not, then, among the doubters -
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.
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.
But if thou art in doubt as to that which We have revealed to thee, ask those who read the Book before thee. Certainly the Truth has come to thee from thy Lord, so be not thou of the doubters.
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.
