The third fraudulent argument of this disbelieving group is that the Islamic law states that a person, who has 99 things of disbelief and one thing of Islam in his personality, should not be labelled as a disbeliever. Firstly, this flimsy argument is the worst and the weakest of all. If a person gives a call to prayer or performs a prayer of two-Rakah once in the day and worships the idols, blows the clarions or rings the bells in the remaining part of the day for 99 times, he is by this definition a Muslim. Such a person is not a man of faith. Let alone faith, such a person cannot be described as a Muslim by a sensible man.
Secondly, in the light of this definition except the atheists, who deny the very existence of Allah, all other disbelievers, like Hindus, Christians, Jews etc, will have to be described as Muslims. They have one thing in common; they all believe in the existence of Allah. This one thing is one of the most important principles in Islam. The philosophically-inlined disbelievers, or Aryans or similar other people have their own concepts of the unity of, Allah. The Jews and Christians will have to be regarded as very distinguished Muslims because in addition to the unity of Allah they also believe in many of His Scriptures, thousands of His Prophets, the Dooms-day, accountability on the final Day of Judgement, reward, and punishment, Heaven and Hell etc, most of these doctrines being in conformity with Islam.
