الفرقان — Al-Furqan Ayat 57

قُلْ مَآ اَسْـَٔلُكُمْ عَلَيْهِ مِنْ اَجْرٍ اِلَّا مَنْ شَاۤءَ اَنْ يَّتَّخِذَ اِلٰى رَبِّهٖ سَبِيْلًا

Qul mā as'alukum ‘alaihi min ajrin illā man syā'a ay yattakhiża ilā rabbihī sabīlā(n).

"Say, "I do not ask of you for it any payment - only that whoever wills might take to his Lord a way.""
