Plastering the grave and using baked bricks for it

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) forbade plastering the grave, sitting on it, and constructing a building over it.

Anisah, the daughter of Sayyiduna Zayd bin Arqam (may Allah be pleased with him), said: A son of Zayd named Suwayd died, and a slave of his, male or female, bought lime and (baked) bricks for him. Sayyiduna Zayd said: "What do you intend to do with these things?" He said: "I intend to build a structure over the grave and plaster it." He said: "You have acted harshly and spoken idly. Do not bring near the deceased anything that fire has touched."

Hasan bin Salih said: I heard Isa bin Abi Azzah forbid plastering graves; he said: "Do not plaster graves."

Suwayd bin Ghafalah said: When I die, do not announce my death to anyone; do not bring lime, baked brick or wood near me; and let no woman accompany us (in the funeral).

Mughirah said that Ibrahim used to dislike baked bricks.

Ibrahim said that they (the Companions) used to dislike baked bricks in their graves.

Ibrahim said that they (the Companions) used to like unbaked (mud) bricks and dislike baked bricks, and they used to like reeds and dislike other wood.
