Qur’an on Brotherhood, Mending Relations, and Mindfulness of Allah as Means of Attaining Divine Mercy
“The believers are but brethren. So mend relations between your brethren. And be mindful of Allah, in order that you may be granted mercy.” [Qur’an, 49.10]
Commentary from Tafsir al-Jalalayn:
The believers are indeed brothers, in religion. Therefore [always] make peace between your brethren, when they fall into dispute with one another (a variant reading [for the dual form akhawaykum, ‘your two brethren’] has ikhwatakum, ‘your brothers’) and fear God, so that perhaps you might receive mercy.
