سورة الزخرف
لِتَسۡتَوُۥاْ عَلَىٰ ظُهُورِهِۦ ثُمَّ تَذۡكُرُواْ نِعۡمَةَ رَبِّكُمۡ إِذَا ٱسۡتَوَيۡتُمۡ عَلَيۡهِ وَتَقُولُواْ سُبۡحَٰنَ ٱلَّذِي سَخَّرَ لَنَا هَٰذَا وَمَا كُنَّا لَهُۥ مُقۡرِنِينَ
In order that you may mount firmly on their backs, and then may remember the Favour of your Lord when you mount thereon, and say: "Glory to Him who has subjected this to us, and we could never have it (by our efforts)."
