this does not require that the injunctions and prohibitions issued by its members reach every morally accountable person in the world. This is not a condition for conveying the message itself, so how could it be required of what follows from it? Rather, the condition is that morally accountable people have the opportunity to receive them. If they then neglect to seek them out, while the person conveying them has fulfilled his duty, the negligence is theirs, not his.
Likewise, enjoining right and forbidding wrong is not an obligation upon every individual; rather, it is a collective obligation, as the Quran indicates. Since jihad serves to complete this duty, it too is a collective obligation. If no one adequately fulfils it, everyone capable of doing so incurs sin according to their ability, for it is obligatory upon each person according to their ability.
As the Prophet, peace and blessings be upon him, said:
“Whoever among you sees something wrong, let him change it with his hand. If he is unable, then with his tongue. If he is unable, then with his heart—and that is the weakest level of faith.”
