Qur'an 42:23

ذَٰلِكَ ٱلَّذِى يُبَشِّرُ ٱللَّهُ عِبَادَهُ ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ ۗ قُل لَّآ أَسْـَٔلُكُمْ عَلَيْهِ أَجْرًا إِلَّا ٱلْمَوَدَّةَ فِى ٱلْقُرْبَىٰ ۗ وَمَن يَقْتَرِفْ حَسَنَةً نَّزِدْ لَهُۥ فِيهَا حُسْنًا ۚ إِنَّ ٱللَّهَ غَفُورٌ شَكُورٌ

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