Does the prophetic Hadith: “There is no [valid] confederacy in Islam, and any confederacy that existed in the pre-Islamic era of ignorance, Islam has only intensified it,” include da‘wah and jihadi parties and the alliances between them, such as the alliance between Hamas and Islamic Jihad?

There is no disagreement among jurists regarding the nullity of alliances between Muslims if they are based on one party supporting the other, whether in right or wrong, or on inheritance to the exclusion of relatives. As for alliances for good, mutual support in truth, and cooperation in righteousness for those who have no heir, scholars have differed on their permissibility after the hadith: "There is no alliance in Islam, and any alliance that existed in pre-Islamic times, Islam has only strengthened it."

The Hanafis maintained the permissibility of alliances between Muslims for mutual financial responsibility (on the 'aql), inheritance, support, and counsel. They interpreted the hadith as negating alliances based on prohibited pre-Islamic practices. However, the majority of jurists held that pre-Islamic alliances continue only in mutual support for the truth, and that alliances formed after the hadith are abrogated, as the hadith is a abrogator. Others held the permissibility of forming alliances for mutual support in truth, counsel, and cooperation in good, relying on Al-Nawawi's statement that an alliance for obedience to Allah and cooperation in righteousness and piety remains valid and has not been abrogated. They argued that the negation of alliances refers to alliances of inheritance or alliances concerning matters forbidden by Islamic law.
