“The Messenger of Allah ﷺ used to perform Witr and recite: ‘Glorify the Name of your Lord the Most High.’, [Al-A’la (87)] ‘Say: O you disbelievers!” [Al-Kafirun (109)] and ‘Say: Allah is One.”. [Al-Ikhlas (112)] (Using translation from Ibn Mājah 1171)
«كَانَ النَّبِيُّ ﷺ يُوتِرُ بِثَلَاثٍ بِسَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقُلْ يَا أَيُّهَا الْكَافِرُونَ وَقُلْ هُوَ اللَّهُ أَحَدٌ»
