Sura al-Furqān 25:41

وَإِذَا رَأَوْكَ إِن يَتَّخِذُونَكَ إِلَّا هُزُوًا أَهَٰذَا ٱلَّذِى بَعَثَ ٱللَّـهُ رَسُولًا

wa-idhā raʾawka in yattakhidhūnaka illā huzuwan a-hādhā alladhī baʿatha allāhu rasūlan

When they see thee, they treat thee no otherwise than in mockery: "Is this the one whom Allah has sent as a messenger?"

Sura al-Furqān 25:51

وَلَوْ شِئْنَا لَبَعَثْنَا فِى كُلِّ قَرْيَةٍ نَّذِيرًا

wa-law shiʾnā la-baʿathnā fī kulli qaryatin nnadhīran

Had it been Our Will, We could have sent a warner to every centre of population.
