Islam never permits anybody to accept Islam forcefully.
Converting to Islam should be only by studying its basic teaching and believing in it.
If a person has no faith he should not be forced to accept Islam.
But everybody have the responsibility to know what is God’s true message and then to take the wise decision. If he disagree, still he can discuss and clear the doubts.
If it is God’s true message, there is no doubt, it will be the acceptable quality.
If it is human made or edited message, definitely, it will be not perfect religion, because the God’s religion does not deserve to be corrected and edited by human being,
Dear All,
Please note few of these points about Islam.
