Evidence that the time for the festival prayer is like the time for the Duha prayer?

Question : Now, if someone asks, what is the evidence that its time is like the time for the Duha prayer? If a person says that its time is from the rising of the sun?

Answer : We say the evidence for this is two things. The first is that the Prophet (peace and blessings be upon him) and his Rightly Guided Caliphs did not pray it except after the sun had risen the height of a spear. The second is that the time before that is a time of prohibition. The time before that is a time of prohibition, and a time of prohibition cannot be a time for prayer. This applies to all people alike, because a time of prohibition is for a missed prayer for a person who forgot it, for example, or something similar to that.
