And those who believed after [the initial emigration] and emigrated and fought with you - they are of you. But those of [blood] relationship are more entitled [to inheritance] in the decree of Allāh.1 Indeed, Allāh is Knowing of all things.
Translation: Saheeh International (English)
1 This applies to Muslim relatives only. Others may be given by bequest. See 4:11.
Those who believed and accepted the faith amongst the earlier Emigrants and Helpers, who emigrated from the land of disbelief to the land of Islam, and strived in Allah’s path so that Allah’s Word may be the highest and the word of the disbelievers may be the lowest – they are part of you, O believers. They will have the same rights and obligations as you have. Under Allah’s final sacred laws of inheritance, family members are closer to one another than the previous Islamic system of inheritance based on faith and emigration. Allah knows everything. Nothing is hidden from Him. He knows what is best for His servants and legislates what is in their well being.
