Musannaf Ibn Abi Shaybah 12123 — Plastering the grave and using baked

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."
