ذٰلِكَ الَّذِيْ يُبَشِّرُ اللّٰهُ عِبَادَهُ الَّذِيْنَ اٰمَنُوْا وَعَمِلُوا الصّٰلِحٰتِۗ قُلْ لَّآ اَسْـَٔلُكُمْ عَلَيْهِ اَجْرًا اِلَّا الْمَوَدَّةَ فِى الْقُرْبٰىۗ وَمَنْ يَّقْتَرِفْ حَسَنَةً نَّزِدْ لَهٗ فِيْهَا حُسْنًا ۗاِنَّ اللّٰهَ غَفُوْرٌ شَكُوْرٌ ( الشورى: ٢٣ )

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 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, Allah is Forgiving and Appreciative. (Ash-Shuraa  : 23)

That is the good news that Allah gives to His servants who believed and did righteous deeds. Say, “I do not ask you any fee for it, except the love of kinship.” And whoever performs a good act, We will increase for him goodness therein. Surely Allah is Most-Forgiving, Very-Appreciative.
