The time of the zenith prayer, from its beginning to its end
When does the time of the zenith prayer begin and when does it end according to the four imams?

It begins when the sun passes its zenith and lasts until a thing's shadow reaches twice its length, apart from the shadow at zenith.

Maliki
It begins with the sun's decline from the zenith; its chosen time lasts until each thing's shadow equals it, then it is shared with the ʿaṣr for the span of one prayer, and its time of necessity extends to sunset.
