"I watched the Messenger of Allah ﷺ- twenty times- reciting in the two rak'ahs after maghrib 'Say: O you disbelievers' and 'Say: He is Allah, (the) One.'" (Using translation from Nasāʾī 992)
«رَمَقْتُ النَّبِيَّ ﷺ عِشْرِينَ مَرَّةً فَقَرَأَ فِي الرَّكْعَتَيْنِ بَعْدَ الْمَغْرِبِ وَفِي الرَّكْعَتَيْنِ قَبْلَ الْفَجْرِ قُلْ يَا أَيُّهَا الْكَافِرُونَ وَقُلْ هُوَ اللهُ أَحَدٌ»
