Sura 18 Al-Kahf (The Cave), aya 24

1. إِلَّا أَنْ يَشَاءَ اللَّهُ ۚ وَاذْكُرْ رَبَّكَ إِذَا نَسِيتَ وَقُلْ عَسَىٰ أَنْ يَهْدِيَنِ رَبِّي لِأَقْرَبَ مِنْ هَٰذَا رَشَدًا

   Except (when adding), "If Allah wills." And remember your Lord when you forget (it) and say, "Perhaps my Lord will guide me to what is nearer than this to right conduct."

   18:24
