“And who speaks fairer than he who calls unto God
and does righteousness and says, ‘Surely I am of those that submit’?

Not equal are the good deed and the evil deed. Repel with that which is
fairer and behold, he between whom and thee there is enmity shall be as if he
were a loyal friend.

Yet none shall receive it, except the steadfast; none shall receive it,
except a man of mighty fortune.” [Qur’an, 41.33-35]

وَمَنْ أَحْسَنُ قَوْلًا مِمَّنْ دَعَا إِلَى اللَّهِ وَعَمِلَ صَالِحًا
وَقَالَ إِنَّنِي مِنَ الْمُسْلِمِينَ (33) وَلَا تَسْتَوِي الْحَسَنَةُ وَلَا
السَّيِّئَةُ ادْفَعْ بِالَّتِي هِيَ أَحْسَنُ فَإِذَا الَّذِي بَيْنَكَ
وَبَيْنَهُ عَدَاوَةٌ كَأَنَّهُ وَلِيٌّ حَمِيمٌ (34) وَمَا يُلَقَّاهَا إِلَّا
الَّذِينَ صَبَرُوا وَمَا يُلَقَّاهَا إِلَّا ذُو حَظٍّ عَظِيمٍ (35) [فصلت/33-35]
