Is the punishment of the grave alleviated for the disobedient Muslim?

Question : And is it alleviated? For the disobedient believer?

Answer : The answer is yes, it may be alleviated. The Prophet (peace and blessings be upon him) passed by two graves and said, "They are being punished, and they are not being punished for a small matter. Yes, it is a great matter. One of them did not ensure cleanliness, or he said, did not purify himself from urine. And the other used to go about spreading talebearing." Then he took a fresh branch, split it in two, and stuck one in each grave. He said, "Perhaps it will alleviate their punishment as long as they do not dry out." This is evidence that it may... what?
It may be alleviated. The punishment in it may be alleviated. But what is the connection between these two branches and the alleviation of the punishment for these two punished ones? It was said that the two branches glorify Allah as long as they do not dry out. And glorification alleviates the punishment of the deceased. They derived from this inferred cause, which may be unlikely, that it is recommended for a person to go to the graves and glorify Allah there in order to alleviate their punishment. Some scholars said this reasoning is weak. Because the two branches glorify Allah whether they are fresh or dry. By the saying of Allah the Exalted: And he heard the glorification of the pebbles in the presence of the Messenger (peace and blessings be upon him), even though the pebbles are dry. So what is the cause?
The cause is that the Messenger (peace and blessings be upon him) hoped from Allah the Mighty and Majestic that He would alleviate their punishment as long as these two branches remained fresh, meaning for a period that is not long, which is what the Messenger (peace and blessings be upon him) hoped for. And that was in order to warn against their actions, because their actions are great, as came in the narration. Indeed, it is great. One of them did not ensure cleanliness from urine, and if he does not ensure cleanliness from urine, he prays with purity or without purity. And the other goes about spreading talebearing, corrupting the servants of Allah, may Allah protect us, and sowing enmity and hatred between them. So the matter is great. And this is the closest view. The closest view is that it is a temporary intercession as a warning to the community, not that the Messenger (peace and blessings be upon him) is exempted from permanent intercession, but rather as a warning to the community.
