Al 'Imran, 159 Ayah
3:159
فَبِمَا رَحۡمَةٖ مِّنَ ٱللَّهِ لِنتَ لَهُمۡۖ وَلَوۡ كُنتَ فَظًّا غَلِيظَ ٱلۡقَلۡبِ لَٱنفَضُّواْ مِنۡ حَوۡلِكَۖ فَٱعۡفُ عَنۡهُمۡ وَٱسۡتَغۡفِرۡ لَهُمۡ وَشَاوِرۡهُمۡ فِي ٱلۡأَمۡرِۖ فَإِذَا عَزَمۡتَ فَتَوَكَّلۡ عَلَى ٱللَّهِۚ إِنَّ ٱللَّهَ يُحِبُّ ٱلۡمُتَوَكِّلِينَ ١٥٩
Fabimā Raĥmatin Mina Al-Lahi Linta Lahum ۖ Wa Law Kunta Fažžāan Ghalīža Al-Qalbi Lānfađđū Min Ĥawlika ۖ Fā`fu `Anhum Wa Astaghfir Lahum Wa Shāwirhum Fī Al-'Amri ۖ Fa'idhā `Azamta Fatawakkal `Alá Al-Lahi ۚ 'Inna Al-Laha Yuĥibbu Al-Mutawakkilīna
So by mercy from Allah, [O Muhammad], you were lenient with them. And if you had been rude [in speech] and harsh in heart, they would have disbanded from about you. So pardon them and ask forgiveness for them and consult them in the matter. And when you have decided, then rely upon Allah . Indeed, Allah loves those who rely [upon Him].
