There is a Hadith in Musnad Ahmad that Nabi (sallallahu ‘alayhi wa sallam) used to recite Surah Zilzal and Surah Kafirun in two rak’ahs after Witr.
Is this Hadith authentic?
Imam Ahmad (rahimahullah) has recorded this Hadith. Imam Ibn Khuzaymah and Imam Ibn Hibban (rahimahumallah) have declared the Hadith authentic.
(Musnad Ahmad, vol. 5 pg. 260, Sahih Ibn Khuzaymah, Hadith: 1104, Sahih Ibn Hibban; Al Ihsan, Hadith: 2635 and 2640)
And Allah Ta’ala Knows best.
