READ BETWEEN THE LINES

Muslims believe in what was revealed to thier Blessed Prophet Muhammed(SAW) and what was revealed before him to other prophets of Allah. they therefore haved a comprehensive knowlegde .

You can never be a truly knowledgeable Muslim if you do not believe in the Other Prophets of Allah.
Islam thus encourages a Muslim to be an all rounder as it were.

To learn what the message of the other Prophets Is. He will discover that all the prophets taught ONENESS of Allah. He will then be able to confront anybody that holds a contrary view or challenges Him, from a position of knowledge.

If you do not know the rteal teachings of Prophet Isa (ASW), for example , If a Christian friend tells you he said he is Gos, you might believe your friend. But, if you read prophet Isa teachings, you would have discovered that nowhere in his teachings did he ever say This.

If you do not know the real story of Prophet Sulayman(ASW), you will only believe that he was known majorly for being a romantic womanizer, whom kept a harem full of woman. the real reason for this would have being lost- that he was granted immense power, wealth and knowledge by Allah and he loved Allah so much that all he desired to do was raise as many children as Jihadists for Allah's cause.

Endeavor to know the deeper meanings of things.
things are never as they seem to appear. only people with deeper knowledge read between the lines.

Prayer: O Allah I seek Thy protection from entertaining doubts about the truth after acquiring belief; I seek Thy protection from the accused Devil and I seek Thy Protection from the mischief of the Day of Judgement.
