Sura 6 Al-An'am (The Cattle), aya 147

1. فَإِنْ كَذَّبُوكَ فَقُلْ رَبُّكُمْ ذُو رَحْمَةٍ وَاسِعَةٍ وَلَا يُرَدُّ بَأْسُهُ عَنِ الْقَوْمِ الْمُجْرِمِينَ

   So if they deny you, (O Muhammad), say, "Your Lord is the possessor of vast mercy; but His punishment cannot be repelled from the people who are criminals."

   6:147
