(a) It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) fell asleep in his prostration and sleep overcame him, until the sound of snoring could be heard. I said: O Messenger of Allah, you fell asleep. He (peace and blessings be upon him) said: "Ablution is due upon one who sleeps on his side, and whoever lays down his side (that is, lies down), his joints become relaxed."
(b) Some narrated in the hadith: "Ablution is due upon one who sleeps lying down; indeed, whoever lies down, his joints become relaxed."
