Introduction to the Surah

Muslim reported from Jabir that the Prophet (s) recited Suratul Kafirun and Suratul Ikhlas in the two Rakat after Tawaf. Muslim reported, on the authority of Abu Hurairah that the Prophet (s) used to recite these two surahs in the Sunnah Rakah of Fajr prayer (Subhi).

Ahmad Ibn Hanbal reported that Ibn Umar said that he heard the Prophet (s) reciting these two surahs in the two rakat of before Fajr and two rakah after Maghrib congregation, over twenty or ten times.

Ahmad Ibn Hanbal reported from him that he noted the Prophet (s) reciting these two surah in the two rakah before fajr for twenty-four or twenty-five times. Musnad also reported from him that he saw the Prophet (s) reciting these verses in the two rakah continuously for one month. This hadith is quoted by Ibn Majah, Nasa'i and Tirmidhi as well.

Recitation before Bedtime

Ahmad Ibn Hanbal reported that  Naufal bin Muawiyah said: "The Prophet (s) once told me, 'Bring my step daughter Zainab up in your house'. Once I went to the Prophet (s), he asked me about the child. When I told him that I had left her with her mother, he asked me the purpose of my visit. I said, 'I have come to learn from you something to recite before going to bed.' He directed me to recite Qul ya Ayyuhal Kafirun (the entire chapter) before I sleep as it contains a repudiation of polytheism.
Tabarani also reported that the Prophet (s) directed Harith bin Jabal also to recite this Surah at bedtime. According to another hadith quoted by Tabarani, the Prophet (s) himself used to recite this Surah when going to bed.

Tafsir Ibn Kathir
Tafsir:

The Declaration of Innocence from Shirk

This Surah is the Surah of disavowal from the deeds of the idolators. It commands a complete disavowal of that.

Allah's statement,
﴿ﻗُﻞْ ﻳﺄَﻳُّﻬَﺎ ﺍﻟْﻜَـﻔِﺮُﻭﻥَ ﴾
(Say: "O disbelievers!'') includes every disbeliever on the face of the earth, however, this statement is particularly directed towards the disbelievers of the Quraysh. It has
been said that in their ignorance they invited the Messenger of Allah to worship their idols for a year and they would (in
turn) worship his God for a year.
