Yahya bin Sbyh يحيى بن صبيح · Funerals (Kitab Al-Jana'iz)

There were three times at which the Messenger of Allah (ﷺ) used to forbid us to pray or bury our dead - when the sun begins to rise till it is fully up, when the sun is at its height midway till it passes the meridian, and when the sun draws near to setting till it sets, or as he said.
