﴿ ثُمَّ ءَاتَيْنَا مُوسَى ٱلْكِتَٰبَ تَمَامًا عَلَى ٱلَّذِىٓ أَحْسَنَ وَتَفْصِيلًۭا لِّكُلِّ شَىْءٍۢ وَهُدًۭى وَرَحْمَةًۭ لَّعَلَّهُم بِلِقَآءِ رَبِّهِمْ يُؤْمِنُونَ ﴾

“AND ONCE AGAIN: We vouchsafed the divine writ unto Moses in fulfilment [of Our favour] upon those who persevered in doing good, clearly spelling out everything, and [thus providing] guidance and grace, so that they might have faith in the [final] meeting with their Sustainer.”
