The Bedouin tribes from the areas surrounding Madinah were not mature in understanding. When they used to come to the meetings of the Prophet Muhammad, they did not address him as ‘O Prophet of God’, but rather as ‘O Muhammad.’ Their manner of speech was not modest or humble, but overbearing. Such behaviour was prohibited. A Prophet is God’s representative in this world. Rudeness to him of this nature amounts to rude behaviour towards God, which renders a man absolutely worthless. After the demise of the Prophet Muhammad, the guidance brought by him stands in his place. Now this divine guidance necessitates obedience just as obedience to the Prophet personally was required during his lifetime. Fear of God makes a man serious. If fear of God really enters a man’s heart, he will come to know automatically, as a matter of instinct, all those realities of which others remain unaware in spite of being informed of them.
