Times of Prohibition for the Obligatory and Voluntary Prayers

Question:
The questioner, Abu 'Abdullah, asks: Are the times of prohibition for prayer specific to the obligatory prayer, or do they also apply to the voluntary prayer?

Answer:
Both. The obligatory prayer is performed at any time. If one forgets a prayer or sleeps through it, he should pray it when he remembers it; there is no expiation for it other than that. The obligatory prayer is performed at any time when one remembers it or is able to perform it, and he should not delay it. As for the voluntary prayer, it is not performed during the times of prohibition. These are after the Fajr prayer until the sun rises, after it rises until it has risen the height of a spear, while it is standing in the middle of the sky until it declines, and after the 'Asr prayer until the sun sets. It is also suspended until the sunset is complete. There are five times of prohibition in which the voluntary prayer is not performed. Yes.
