What are the instances described by Uqba b. 'Amir wherein Allah's Messenger (peace be upon him) forbade us to pray or bury our dead?
 Uqba b. 'Amir said:                      There were the times at which Allah's Messenger (may peace be upon him) forbade 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 at midday till it passes over the meridian, and when the sun draws near to setting till it sets.
