Hadith 31-76

وَبِهذَا الإِسنادِ قالَ: قالَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَآلِهِ: اِصطَنِعِ الخَيْرَ إِلى مَن هُوَأَهْلُهُ وَإِلى مَن هُوَغَيْرُ أَهْلِهِ فَإِنْ لَمْ تُصِب مَن هُوَأَهْلُهُ فَأَنتَ أَهْلُهُ.

According to the same documentation, God’s Prophet (S) said, “Do good to all people whether they deserve it or not. If the one to whom you do good does not deserve it, you deserve to do good yourself.”
