Yusuf Ali
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.

Sahih International
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.

Shakir
But if you are in doubt as to what We have revealed to you, ask those who read the Book before you; certainly the truth has come to you from your Lord, therefore you should not be of the disputers.

Pickthall
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.

محمد جالندھری
