The greatest sin is disbelief

 

 The greatest sin is disbelief.  What is disbelief?  Denying God is disbelief.  Denying the Messenger is disbelief. Denying the Qur'an is disbelief.  Denial of the Hereafter is disbelief.  Denying angels is infidel.  When man was suffering from disbelief, God took pity on the plight of man and made His beloved Prophet a guide.  Then the Prophet (peace and blessings of Allaah be upon him) told you to accept Allaah with one eye and be lost in His praise.  Then Allah's Apostle told you the secret of the place of Prophethood.  Donated a great book like Quran.  The knot of death and the Hereafter has opened before you.  God's beloved creatures were introduced to the angels and invited you to give up your superstitions and become a priest of one God and become a believer.  Some of them accepted and accepted the wealth of faith out of humility but the people of disbelief!  Your intellect has deceived you and you are still deprived of faith and Islam.  Though you have torn the layers of the sea.  The treasures of the earth have been opened.  Thou hast subdued the mountains and the plains.  The distances of years have been overlooked.  It is as if the body is busy day and night for convenience, but my friend's car should be adorned with faith as well.  Do not bargain for the Hereafter in exchange for this lowly world.

 O lost people of the world!  Why are you stuck in the valleys of disbelief?  Why be deceived by Satan?  Remember, your welfare is not in disbelief, your welfare is in accepting Islam.  Your well-being is in faith.  Your fate is in the Qur'an.  Your salvation is in slavery Mustafa.  my friend !  When it is known that one cannot be saved without obeying God, His Messenger and the Qur'an, then how long is the delay in repentance?  Prostrate yourself before God today and shed the tears of remorse from your heart and leave disbelief.  Unbelief is the antithesis of faith and a person is deprived of faith if he does not repent of disbelief and come to Allah.  Unbelief is utter ignorance because man does not recognize the blessings bestowed by Allah.  That is why Allaah says (interpretation of the meaning):

 How can you disbelieve in Allah when you are nothing?  He gave you life.  Then He will strike you, and He will give you life again, and to Him you will be returned.
