Prophet Muhammad is the most courageous, not a coward. The right speaks, though it is bitter, does not even harbor hatred and malice in the heart of the Messenger of Allah.
The Prophet is not a coward just for not mentioning names. The Prophet is the most courageous man. No one is more courageous than the Prophet Muhammad. The Messenger of Allah was the leader of the Mujahideen. One of the highest jihad is the Prophet Muhammad.
A friend said, "The most courageous man in the eyes of a friend is the closest to the Prophet Muhammad. Because the Prophet during the war is always closest to the ranks of the unbelievers ". The Prophet Muhammad was on his donkey, spinning his spear and saying "I am the Prophet, not a lie, I am the grandson of Abdul Muttalib." That is, the courage of the Prophet Muhammad.Since that, the courageous friend approached with the Messenger of Allah, brave.
Prophet Muhammad SAW was the leader of the mujahidin, but Jihad Rasulullah saw no idleness, insults and wickedness. Because of that, follow and reverence the knowledge of the Prophet, akhlaknya, jihadnya, dakwahnya, amar makrufnya, and nahi mungkarnya. For if forbidding an unjust case with munkar then becomes two munkar.
Doing amar makruf and nahi mungkar in a way that is haram is haram. So also eat human flesh in da'wah method. Ghibah, namimah, gossip, lies, insults and insults, can not be used as da'wah method. Can not get rid of immoral with immoral. Because it will be two immoral.
