“This is concerning my question before abu ‘ Abd Allah (a.s.), ‘What is the meaning of the words of the Holy Prophet, . . commitment of a person of the lowest position among them becomes a commitment of all of them (Muslims)?’” He (the Imam) replied, ‘It means, if the Muslim army surrounds a stronghold of the pagans and a man comes up saying, “Grant me immunity so I can debate your man.” If a man of the lowest position in the Muslim army grants him immunity, it becomes obligatory for all of them to fulfill that commitment.’”
