سنن نسائی · Hadith 1745

Muhammad bin Bashshar informed us, he said: “Abu Dawud narrated to us from Shu’bah, from Qatadah, who said: I heard ‘Azarah narrating from Saeed bin ‘Abdur Rahman Ibn Abza, from his father, that the Messenger of Allah صلی اللہ علیہ وآلہ وسلم used to recite in Witr: ‘Glorify the Name of your Lord, the Most High;’ and: ‘Say: you disbelievers!;’ and: ‘Say: He is Allah, (the) One.’ And when he finished, he would say: ‘Subhanal-Malikil-Quddus (Glory be to the Sovereign, the Most Holy)’ three times.” (Sahih)
