إِلَّا أَن يَشَاء اللَّهُ وَاذْكُر رَّبَّكَ إِذَا نَسِيتَ وَقُلْ عَسَى أَن يَهْدِيَنِ رَبِّي لِأَقْرَبَ مِنْ هَذَا رَشَدًا
[18:24]
Unless Allah pleases; and remember your Lord when you forget and say: Maybe my Lord will guide me to a nearer course to the right than this.
Without adding, "So please Allah!" and call thy Lord to mind when thou forgettest, and say, "I hope that my Lord will guide me ever closer (even) than this to the right road."
Except if Allah will. And remember thy Lord when thou forgettest, and say: It may be that my Lord guideth me unto a nearer way of truth than this.
