2.2.3 The Second Section: The obligations of the Muslims and mutual support among them
11- Verily, the believers shall not leave any indebted person from among them without him being provided for, on a fair and reasonable basis, in respect to ransom or blood money. 12- A believer shall not enter into alliance with the Mawla (freed slave who maintains loyalty or a client) of a believer without the latter’s consent.
13- The God-fearing believers stand together against the one who rebels or seeks to insert injustice, crime, aggression or corruption among the believers. Their hands are all united against him, even if he was the son of one of them.
14- A believer shall not kill another believer for the sake of a disbeliever.
15- (A believer) shall not support a disbeliever against a believer.
16- The protection of Allah is one and its extension upon the least of them is applied to all of them.
17- The believers are allies and protectors of one another to the exclusion of the people.
18- Whoever from the Jews follows us; receives support and assistance. They are not wronged and support is not provided to others against them.
19- The peace of the believers is one. No peace is made by a Muslim separate to another Muslim in the fighting in the way of Allah, except upon the basis of mutual even handedness and justice.
20- In respect to every military attachment that goes out with us, it will be followed one after the other.
