Shaikh Ibn ul-‘Uthaymeen rahimahullah was asked:
How true is what is said: that the one who dies in Ramadan or on the day of Jummah will not be punished with the punishment of the grave?
The punishment in the grave is established for everyone who deserves it whether they died on Jummah or Ramadan or in another time. So like this, the Muslims say in their prayer, in every prayer of their prayers, in the last Tashahud: I seek refugee in Allah from the punishment of the Hell-fire, from the punishment of the grave, from the trails of life and death and from the trial of the Anti-Christ. Except for one who dies struggling in Allah’s path, then the two Angels who ask about a person’s religion, Lord, and Prophet do not come to him. This is because the flashing of the sword over his head is a greater test for him and an evidence that he is a believer. Otherwise, he would not expose his neck to the enemies of Allah”
