It was narrated from ‘Ali (رضي الله عنه) from the Prophet (ﷺ) that On the day of al-Ahzab, he was at one of the crossing points of the ditch and he said: `They distracted us from the middle prayer until the sunset; may Allah fill their graves and their houses - or their bellies and their houses - with fire.”
