The hadith of Sayyiduna Ibn Abbas and Sayyiduna Rifa'ah (may Allah be pleased with them) regarding prostrating on the forehead has already passed.
Likewise, the hadith of Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) has also passed, in which his prostrating on his forehead in mud is mentioned.
It is narrated from Sayyiduna Khabbab bin al-Aratt (may Allah be pleased with him) that we complained to the Messenger of Allah (peace and blessings be upon him) about the intense heat of the sun, that our foreheads and palms were burning, but he (peace and blessings be upon him) did not accept our complaint.
