There are three times during which neither prayer should be performed nor a dead be buried

 219. ´Ulaiy bin Rabah said: I heard ´Uqbah bin ´Amir Al-Juhni say: ´´There are three times during which the Messenger of Allah salla alayhi wa sallam forbade us to pray, or to bury our dead: When the sun begins to rise until it becomes high, when the sun is at its heights at midday until it passes meridian, and when the sun draws near setting until it sets.´´
