May I say that we need to also remember that our beloved Muhammad was a leader and in that capacity how could he have taken when he knew his people were suffering? Before he received prophethood, he lived a modest life but was it that of an ascetic? I don't think the issue of choice and force is a fair one to discuss here since he was generous and fair in sharing whatever was acquired by the will of Allah (SWT), fulfilling the duties of his makaam. Leaders should take heed of the standard set by him.
