لَرَءُوفٌ laraūfun · Full of Kindness

And thus We have made you a median [i.e., just] community that you will be witnesses over the people and the Messenger will be a witness over you. And We did not make the qiblah which you used to face except that We might make evident who would follow the Messenger from who would turn back on his heels. And indeed, it is difficult except for those whom Allāh has guided. And never would Allāh have caused you to lose your faith [i.e., your previous prayers]. Indeed Allāh is, to the people, Kind and Merciful. (Surah Al-Baqarah, 2:143)

وَمِنَ النَّاسِ مَن يَشْرِي نَفْسَهُ ابْتِغَاءَ مَرْضَاتِ اللَّهِ وَاللَّهُ رَءُوفٌ بِالْعِبَادِ ٢٠٧

And of the people is he who sells himself, seeking means to the approval of Allāh. And Allāh is Kind to [His] servants. (Surah Al-Baqarah, 2:207)

The [unmarried] woman or [unmarried] man found guilty of sexual intercourse - lash each one of them with a hundred lashes, and do not be taken by pity for them in the religion [i.e., law] of Allāh, if you should believe in Allāh and the Last Day. And let a group of the believers witness their punishment. (Surah An-Nur, 24:2)
