Sayyidah Aishah bint Sa'd (may Allah be pleased with her) narrates: Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) washed the body of Sayyiduna Sa'id bin Zayd (may Allah be pleased with him) at al-Aqiq. Then they lifted his body and brought it. Sayyiduna Sa'd (may Allah be pleased with him) came walking until, when he came opposite his house, he went inside, took a bath (ghusl) and then came out and said: "I did not take a bath because I had washed Sayyiduna Sa'id (may Allah be pleased with him); rather, I took a bath because of the heat."
Imam al-Tabarani recorded this narration, and its chain contains a narrator whom I do not know.
