The time of the prohibition of prayer after Fajr

Question:
He says: Honorable Shaykh, may Allah grant you success, the prohibition of prayer after the Fajr prayer until the sun rises and reaches the height of a spearhead has been reported. What is meant by this?

Answer:
It is known, therefore, you do not pray a voluntary prayer. As for the obligatory prayer, you pray it at any time, whether within its time, or if you slept or forgot it, you make it up when you remember or wake up immediately. Making up the prayer has no specific time limit because you pray it at any time. As for voluntary prayers, you do not pray them during the prohibited times. Is his statement "the sun rises the height of a spearhead" a specific time, such as a quarter of an hour or something else?
It means it rises above the horizon by the length of a spear. The spear that was known among the Arabs, which they used to stab with, meaning a stick with a pointed tip or one with a sharp iron point, which they throw at those they want to stab or who stab them, and they reach them from a distance on horseback or on foot. This is the spear. So the report is approximate, meaning if the sun rises above the horizon, then prayer becomes permissible at that time when it rises above the horizon. It is not determined by the hour, but by the distance of the sun from the horizon. So as long as it is on the horizon, do not pray. When it rises and separates from the horizon, then prayer becomes permissible at that time.
