ভূমিকা
The reason is that the enemy is identified, his bad intentions are clear, his strength is recognized and his goals are well-known. His enmity is written on his forehead and all are prepared for him to commit some kind of atrocity. For this reason man is always ready to defend himself against this enemy. Man never tells him his secrets. He is completely prepared to carefully protect himself against the danger that this enemy poses.
One the other hand, the unknown enemy, however small and powerless he may be, can cause serious damage because he pretends to be a friend or at least pretends to be indifferent. He can cause irreconcilable damage and at the same time not lose anything. Such an enemy will remain a friend even if his bad intentions are made clear. The reason for this is that the victim considers the enemy to be one of his own. His false vows will be accepted and the victim will be tricked by his excuses.
The enemy will then persist with his evil deeds. The hypocrites gained the love and respect of the early Islamic leaders and common Muslims by pretending to be Muslim. Because they were considered Muslim, people did not look at them suspiciously and the atrocities that they committed were kept in the dark. If they were ever exposed they would swear that they were innocent and thus their evil actions would be covered up.
The hypocrites would use their oaths to hide their disbelief and would therefore protect themselves from punishment. Islam’s Most Dangerous Enemy The Prophet of Islam (S), in one of his treasured speeches, introduced the hypocrites as Islam's most dangerous enemy. He even said that they were Islam's only enemy.
