Surah Al-Imran, ayah 73

وَلَا تُؤۡمِنُوٓاْ إِلَّا لِمَن تَبِعَ دِينَكُمۡ قُلۡ إِنَّ ٱلۡهُدَىٰ هُدَى ٱللَّهِ أَن يُؤۡتَىٰٓ أَحَدٞ مِّثۡلَ مَآ أُوتِيتُمۡ أَوۡ يُحَآجُّوكُمۡ عِندَ رَبِّكُمۡۗ قُلۡ إِنَّ ٱلۡفَضۡلَ بِيَدِ ٱللَّهِ يُؤۡتِيهِ مَن يَشَآءُۗ وَٱللَّهُ وَٰسِعٌ عَلِيمٞ ٧٣

Walā tu'minū illā liman tabi'a dīnakum qul innal-hudā hudallāhi an yu'tā ahadum mithla mā ūtītum aw yuhājjūkum 'inda rabbikum qul innal-fadla biyadillāhi yu'tīhi man yashā'u wallāhu wāsi'un 'alīm

And do not trust except those who follow your religion." Say, "Indeed, the [true] guidance is the guidance of Allāh. [Do you fear] lest someone be given [knowledge] like you were given or that they would [thereby] argue with you before your Lord?" Say, "Indeed, [all] bounty is in the hand¹³² of Allāh - He grants it to whom He wills. And Allāh is all-Encompassing and Wise."
