What should I do about my suffering from the signs of the Hour that began in 1993, due to my belief that I am a polytheist and that I have sexual and impure thoughts about Allah, which makes me fear entering Hellfire for thousands of years and suffering the torment of the people of Lut?

We advise you to seek refuge in Allah from the accursed Shaytan (Satan), turn your mind away from negative thoughts, and occupy yourself with beneficial knowledge, productive work, and permissible recreation. Befriend righteous sisters and avoid seclusion and isolation. Repent to Allah with sincere repentance and increase in good deeds and remembrance (dhikr), for this is a cause for forgiveness and mercy, as Allah Almighty says: "But whoever repents after his wrongdoing and makes amends, indeed, Allah will accept his repentance. Indeed, Allah is Forgiving and Merciful." Beware of despairing of Allah's mercy, for He is Forgiving, Oft-Pardoning, and Merciful; He forgives all sins, as Allah Almighty says: "Say, 'O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah. Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.'" There is no harm in consulting psychiatrists.
