The Messenger of Allah ﷺ used to pray thirteen rakahs during the night.
كان رسول الله ﷺ يصلي من الليل ثلاث عشر ركعة.
Bukhari narrated it in the chapter on tahajjud (1138), and Muslim in the chapter on the prayer of travelers (764), both from the hadith of Shubah, who said, Abu Jamra narrated to me, from Ibn Abbas, and he related it. Abu Jamra, with a jeem and a raa, is Dubai, whose name is Nasr bin Imran bin Isam Dubai, well known by his kunya.
