What is the reason for the inability to hear the Qur’an, to seek forgiveness (Istighfar) and glorify Allah (Tasbih), for performing prayers quickly, for feeling distress and suffocation, and for the inability to read the Qur’an?

What you are feeling is a temptation from Satan, so strive against this feeling and recall that happiness and comfort lie in obedience to Allah and seeking His pleasure. Continue with your acts of worship and increase in supererogatory acts. Be diligent in achieving devotion during prayer and in reading and contemplating the Quran. Strive hard in supplication for Allah to turn away this evil matter from you. Through striving, supplication, abundant remembrance of Allah, and keeping good company, this feeling will vanish, your heart will be gladdened, and it will find tranquility in the remembrance of Allah, "Those who have believed and whose hearts are assured by the remembrance of Allah. Unquestionably, by the remembrance of Allah hearts are assured."
