Surah Aali Imran (The Family of Imran), Verse 159

فَبِمَا رَحْمَةٍ مِّنَ اللّٰهِ لِنْتَ لَهُمْ وَلَوْ كُنْتَ فَظًّا غَلِیْظَ الْقَلْبِ لَانْفَضُّوْا مِنْ حَوْلِكَ فَاعْفُ عَنْهُمْ وَاسْتَغْفِرْ لَهُمْ وَشَاوِرْهُمْ فِی الْاَمْرِ فَاِذَا عَزَمْتَ فَتَوَكَّلْ عَلَی اللّٰهِ اِنَّ اللّٰهَ یُحِبُّ الْمُتَوَكِّلِیْنَ ۟

Fabimaa rahmatim minal laahi linta lahum wa law kunta fazzan ghaleezal qalbi lanfaddoo min hawlika fa'afu 'anhum wastaghfir lahum wa shaawirhum fil amri fa izaa 'azamta fatawakkal 'alal laah; innallaaha yuhibbul mutawak kileen

“It is part of the Mercy of Allah that thou dost deal gently with them Wert thou severe or harsh-hearted, they would have broken away from about thee: so pass over (Their faults), and ask for (Allah's) forgiveness for them; and consult them in affairs (of moment). Then, when thou hast Taken a decision put thy trust in Allah. For Allah loves those who put their trust (in Him).”
