The gravels adjure the person when removes them from the mosque.
Sunan Abi Dawud Book 2, Hadith 70
← Previous Hadith It was said that when a man removed gravels from the mosque, they adjured him.

Sunan Abi Dawud Book 2, Hadith 69 Next Hadith → The Prophet (ﷺ) said: The rewards of my people were presented before me, so much so that even the reward for removing a mote by a person from the mosque was presented to me. The sins of my people were also presented before me. I did not find a sin greater than that of a person forgetting the Quranic chapter or verse memorised by him.
