It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said to me: "O Ali! Do not sit facing the sun, for facing it causes illness, and turning your back to it is a remedy and a means of healing."
[Musnad al-Harith (Bughyat al-Bahith): 2442. Its chain contains the narrator Hammad bin Amr al-Nasibi, who is a liar and fabricator, and because of him this report is mawdu' (fabricated).]
