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

This it is which Allah announceth unto His bondmen who believe and do good works. Say (O Muhammad, unto mankind): I ask of you no fee therefor, save loving kindness among kinsfolk. And whoso scoreth a good deed We add unto its good for him. Lo! Allah is Forgiving, Responsive.
