As for his claim that "Yet, if such bodies are available, then it is neither inevitable nor acceptable on the part of the individuals to assume such a rule, since if government authorities and bodies have performed the task of Da`wah and enjoinment of good and disavowal of evil, then the volunteers' participation with it in performing such a task is highly commendable and legally inevitable. Such participation is in line with the rule of cooperation in good and righteousness and is a form of Shar`i Jihad and worthy guidance.
In short, governmental authorities and bodies would have performed the collective obligation, and thus, participation of others in performing such an obligation becomes a form of supererogatory and voluntary acts, which is one of the best acts of worship and the most cherished by Allah (Exalted be He).
Yet, if governmental authorities and bodies fail to perform the obligation in the best way, others' participation with them in such an obligation becomes compulsory, since the collective obligation is not fulfilled by the authority. Besides, legal proofs affirm that the call for Allah's (Exalted be He) Way, and enjoinment of good and forbidding of evil are among the collective obligations which, if performed by a certain group, the rest of the community are exempted from the obligation, and then participation of the rest of the community becomes a supererogatory act. However, if it is not performed by a sufficient group, the whole community becomes sinful.
