The believers are brothers, so make peace between your brothers and fear Allah so that hopefully you will gain mercy. (Surat al-Hujurat, 10)
Obey Allah and His Messenger and do not quarrel among yourselves lest you lose heart and your momentum disappear. And be steadfast. Allah is with the steadfast. (Surat al-Anfal, 46)
Allah loves those who fight in His Way in ranks like well-built walls. (Surat as-Saff, 4)
Hold fast to the rope of Allah all together, and do not separate. Remember Allah’s blessing to you when you were enemies and He joined your hearts together so that you became brothers by His blessing. You were on the very brink of a pit of the Fire and He rescued you from it. In this way Allah makes His Signs clear to you, so that hopefully you will be guided.(Surah Al ’Imran, 103)
He has laid down the same religion for youas He enjoined on Nuh: that which We have revealed to you and which We enjoined on Ibrahim, Musa and ‘Isa: ‘Establish the religion and do not make divisions in it.’ What you call the idolaters to follow is very hard for them. Allah chooses for Himself anyone He wills and guides to Himself those who turn to Him. (Surat ash-Shura, 13)
Those who were already settled in the abode, and in faith, before they came, love those who have emigrated to them; do not find in their hearts any need for what they have been given; and prefer them to themselves, even if they themselves are needy. It is the people who are safe-guarded from the avarice of their own selves who are successful. (Surat al-Hashr, 9)
Those who have come after them say: "Our Lord, forgive us and our brothers who preceded us in faith, and do not put any rancor in our hearts toward those who believe. Our Lord, You are All-Gentle, Most Merciful." (Surat al-Hashr, 10)
