وَإِذَا لَمْ تَأْتِهِم بِـَٔايَةٍ قَالُوا۟ لَوْلَا ٱجْتَبَيْتَهَا ۚ قُلْ إِنَّمَآ أَتَّبِعُ مَا يُوحَىٰٓ إِلَىَّ مِن رَّبِّى ۚ هَـٰذَا بَصَآئِرُ مِن رَّبِّكُمْ وَهُدًى وَرَحْمَةٌ لِّقَوْمٍ يُؤْمِنُونَ
Wa izaa lam taatihim bi aayatin qaaloo law lajtabai tahaa; qul innamaaa attabi'u maa yoohaaa ilaiya mir Rabbee; haazaa basaaa'iru mir Rabbikum wa hudanw wa rahmatul liqawminy yu'minoon
