Prophet SAW said: Hasten to do good deeds before you are overtaken by one of seven afflictions. He then asked, are you waiting for… and described different calamities. The most severe are:
- Sudden death.
- Ad-Dajjal, who is the worst expected absent.
- The Hour, which will be most grievous and most bitter. [Tirmidhi & authentic]
Imam Abu Hanifa RA cried the whole night reciting:
بَلِ السَّاعَةُ مَوْعِدُهُمْ وَالسَّاعَةُ أَدْهَىٰ وَأَمَرُّ
But the Hour is their appointment [for due punishment], and the Hour is more disastrous and more bitter. [54:46]
