God commands justice, the doing of good, and kindness to kith and kin; and He forbids all shameful deeds, and injustice and rebellion: He instructs you, that you may receive admonition. Fulfill the Covenant of God when you have entered into it, and break not your oaths after you have confirmed them; indeed you have made God your surety; for God knows all that you do.... Whoever works righteousness, man or woman, and has Faith, verily, to him will We give a new Life, a life that is good and pure, and We will bestow on such (workers) their reward according to the best of their actions (16: 90-91, 97).

إِنَّ اللَّهَ يَأْمُرُ بِالْعَدْلِ وَالإِحْسَانِ وَإِيتَاءِ ذِي الْقُرْبَى وَيَنْهَى عَنْ الْفَحْشَاءِ وَالْمُنكَرِ وَالْبَغْيِ يَعِظُكُمْ لَعَلَّكُمْ تَذَكَّرُونَ  وَأَوْفُوا بِعَهْدِ اللَّهِ إِذَا عَاهَدْتُمْ وَلاَ تَنقُضُوا الأَيْمَانَ بَعْدَ تَوْكِيدِهَا وَقَدْ جَعَلْتُمْ اللَّهَ عَلَيْكُمْ كَفِيلاً إِنَّ اللَّهَ يَعْلَمُ مَا تَفْعَلُونَ﴾ ﴿مَنْ عَمِلَ صَالِحًا مِنْ ذَكَرٍ أَوْ أُنثَى وَهُوَ مُؤْمِنٌ فَلَنُحْيِيَنَّهُ حَيَاةً طَيِّبَةً وَلَنَجْزِيَنَّهُمْ أَجْرَهُمْ بِأَحْسَنِ مَا كَانُوا يَعْمَلُونَ

Invite (all) to the way of your Lord with wisdom and beautiful preaching; and argue with them in ways that are best and most gracious; for your Lord knows best, who have strayed from His Path, and who are truly guided (16:125).

ادْعُ إِلَى سَبِيلِ رَبِّكَ بِالْحِكْمَةِ وَالْمَوْعِظَةِ الْحَسَنَةِ وَجَادِلْهُمْ بِالَّتِي هِيَ أَحْسَنُ إِنَّ رَبَّكَ هُوَ أَعْلَمُ بِمَنْ ضَلَّ عَنْ سَبِيلِهِ وَهُوَ أَعْلَمُ بِالْمُهْتَدِينَ

Who is better in speech than one who calls (others) to God, works righteousness, and says: ‘I am one of those who bow in Islam’ . Nor can Goodness and Evil be equal.

Repel (Evil) with what is best. Then the one between whom and you there was hatred will become as it were your friend and intimate! (41:33-34).

وَمَنْ أَحْسَنُ قَوْلاً مِمَّنْ دَعَا إِلَى اللَّهِ وَعَمِلَ صَالِحًا وَقَالَ إِنَّنِي مِنْ الْمُسْلِمِينَ  وَلاَ تَسْتَوِي الْحَسَنَةُ وَلاَ السَّيِّئَةُ ادْفَعْ بِالَّتِي هِيَ أَحْسَنُ فَإِذَا الَّذِي بَيْنَكَ وَبَيْنَهُ عَدَاوَةٌ كَأَنَّهُ وَلِيٌّ حَمِيمٌ
