The Prophet (ﷺ) said: Allah is single (witr) and loves what is single, so observe the witr, you who follow the Qur'an.
Sunan Abi Dawud Book 8, Hadith 1
← Previous Hadith When we came to Medina accompanying the caravan, I used to preach after the dawn prayer, and prostrate on account of the recitation of the Qur'an. Ibn Umar prohibited me three times, but I did not cease doing that. He then repeated (his prohibition) saying: I prayed behind the Messenger of Allah (ﷺ), AbuBakr, Umar and Uthman, they would not prostrate (on account of the recitation of the Qur'an) till the sun had risen.
