Translation
Kathir bin ‘Abdullah bin ‘Amr bin ‘Awf Al-Muzani narrated from his father, that his grandfather said:“I heard the Messenger of Allah (ﷺ) say: ‘On Friday there is a time of the day during which no person asks Allah for something but He will give him what he asks for.’” It was said: ‘When is that time?’ He said: ‘When the Iqamah for prayer (is called), until the prayer ends.’”
