Ash-Shuraa 42:23

ذَٰلِكَ ٱلَّذِي يُبَشِّرُ ٱللَّهُ عِبَادَهُ ٱلَّذِينَ ءَامَنُواْ وَعَمِلُواْ ٱلصَّـٰلِحَٰتِۗ قُل لَّآ أَسۡـَٔلُكُمۡ عَلَيۡهِ أَجۡرًا إِلَّا ٱلۡمَوَدَّةَ فِي ٱلۡقُرۡبَىٰۗ وَمَن يَقۡتَرِفۡ حَسَنَةٗ نَّزِدۡ لَهُۥ فِيهَا حُسۡنًاۚ إِنَّ ٱللَّهَ غَفُورٞ شَكُورٌ 23

It is that of which Allah gives good tidings to His servants who believe and do righteous deeds. Say, [O Muhammad], "I do not ask you for this message any payment [but] only good will through kinship." And whoever commits a good deed - We will increase for him good therein. Indeed, Allah is Forgiving and Appreciative
