It is narrated from the Prophet ﷺ that he used to recite Sabbih isma Rabbika al-Ala in the Witr prayer.
حدثنا محمد بن جعفر حدثنا شعبة وحجاج قال حدثني شعبة قال سمعت قتادة يحدث عن زرارة قال حجاج في حديثه قال سمعت زرارة
ى عن النبي ﷺ أنه كان يوتر بسبح اسم ربك الأعلى
Its isnad is sahih. Zurara, as it appears in the original sources, should correctly be Azra, and this will be corrected in the following isnad. He is Azra bin Abdul-Rahman bin Zurara Khuzai, and he is trustworthy. The hadith was narrated by Nasai, 3/244, no. 1729, in the book of the night prayer, chapter on recitation in Witr, and by Ibn Majah, 1/370, no. 1171, in the book of the establishment of prayer, in full, similarly.
