Is it hard to be like the Prophet Muhammad (pbuh)?

Not that easy. To compare, Prophet Muhammad s.a.w. was chosen by Allah to be our Prophet. There is nobody else better or closer to his standard of patient, pious, sincerity,and etc. If we could perform only 1% of what he practises, I think, we could safely say that at least we will not be thrown in the Hell of Fire. We should be grateful that we are Muslims.
