Is it permissible to engage in remembrance (dhikr) and glorification (tasbih) after Fajr prayer while watching television, and when does the time for Duha end?

Engaging in the remembrance of Allah after Fajr prayer is an act of worship with immense reward. A Muslim sits in their prayer place, remembering Allah until the sun rises, and then performs the Duha prayer. It was narrated by Jabir ibn Samurah that the Prophet, peace and blessings be upon him, "When he prayed Fajr, he would sit in his prayer place until the sun rose well." The time for Duha prayer begins when the sun has risen by the height of a spear (approximately fifteen minutes after sunrise) and ends just before the sun reaches its zenith in the middle of the sky (about ten minutes before Dhuhr). As for watching television during remembrance, its ruling has been detailed in a previous fatwa.
