Al-Anfaal (The Spoils of War)

72. “Verily those who believed and migrated and strove with their properties and their selves in the way of Allah, and those who gave shelter and helped (the strivers), those are friends of one another. And those who believed but they did not migrate, you have not any friendship towards them until they migrate. Yet if they ask your help for (the sake of) religion, then it is your duty to help (them), save against a people with whom you have a treaty; and Allah sees all that you do.”

Those who had Faith and, for the love of Allah and Messenger, separated from their homes and relations, i.e. they migrated from Mecca to Medina, and those who gave shelter to the Emigrants and helped them in war against their enemies, i.e. Ansar (the Helpers), inherit each other.

The Emigrants and the Helpers inherited from each other because of the brethren contract they concluded from the beginning with each other until the time when this matter was abrogated by Surah Al-‘Anfal,No. 8 ,verse 75 , which says:

“...and the blood relatives are nearer to each other...”.

If the believers who did not migrate ask you to help them for the sake of the religion of Allah against infidels, you should help them, except for the group of infidels who have concluded the agreement of non-opposition with you. In this case you cannot help the Muslims in war against them. The verse says:

“Verily those who believed and migrated and strove with their properties and their selves in the way of Allah, and those who gave shelter and helped (the strivers), those are friends of one another. And those who believed but they did not migrate, you have not any friendship towards them until they migrate. Yet if they ask your help for (the sake of) religion, then it is your duty to help (them), save against a people with whom you have a treaty; and Allah sees all that you do.”
