فَاِنْ كُنْتَ فِيْ شَكٍّ مِّمَّآ اَنْزَلْنَآ اِلَيْكَ فَسْـَٔلِ الَّذِيْنَ يَقْرَءُوْنَ الْكِتٰبَ مِنْ قَبْلِكَ ۚ لَقَدْ جَاۤءَكَ الْحَقُّ مِنْ رَّبِّكَ فَلَا تَكُوْنَنَّ مِنَ الْمُمْتَرِيْنَۙ ( يونس: ٩٤ )
Fa in kunta fee shakkim mimmaaa anzalnaaa ilaika fas'alil lazeena yaqra'oonal Kitaaba min qablik; laqad jaaa'akal haqqu mir Rabbika falaa takoonanna minal mumtareen (al-Yūnus 10:94)
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. (Yunus [10] : 94)
1 Mufti Taqi Usmani
So, (O prophet,) even if you are in doubt about what We have sent down to you, ask those who read the Book (revealed) before you. Surely, truth has come to you from your Lord, so never be among those who are suspicious.
