(The Messenger’s Doubt)
If you have any doubt regarding what is revealed to you from your Lord, then ask those who read the previous scripture. Indeed, the truth has come to you from your Lord. Do not be with the doubters.
فَإِن كُنتَ فى شَكٍّ مِمّا أَنزَلنا إِلَيكَ فَسـَٔلِ الَّذينَ يَقرَءونَ الكِتٰبَ مِن قَبلِكَ لَقَد جاءَكَ الحَقُّ مِن رَبِّكَ فَلا تَكونَنَّ مِنَ المُمتَرينَ
fa in kunta fee shakkin mimmaaa anzalnaaa ilaika fas’alil lazeena yaqra’oonal Kitaaba min qablik; laqad jaaa’akal haqqu mir Rabbika fa laa takoonanna minal mumtareen
