Ibn Kathir — introduction to this surah
The Recitation of these Surahs in the Optional Prayers
It has been confirmed in Sahih Muslim from Jabir that the Messenger of Allah recited this Surah (Al-Kafirun) and قُلْ هُوَ اللَّهُ أَحَدٌ (Say: "He is Allah One.'' (Surah: 112)), in the two Rakahs of Tawaf.
It is also recorded in Sahih Muslim in a Hadith of Abu Hurayrah that the Messenger of Allah recited these two Surahs in the two Rakahs (optional prayer) of the Morning prayer.
Imam Ahmad recorded from Ibn Umar that the Messenger of Allah recited in the two Rakahs before the Morning prayer and the two Rakahs after the Sunset prayer on approximately ten or twenty different occasions, قُلْ يَا أَيُّهَا الْكَافِرُونَ(Say: "O Al-Kafirun!'') and قُلْ هُوَ اللَّهُ أَحَدٌ (Say: " He is Allah One.'' (Surah: 112)).
Ahmad also recorded that Ibn Umar said,
"I watched the Prophet twenty-four or twenty-five times reciting in the two Rakahs before the Morning prayer and the two Rakahs after the Sunset prayer, قُلْ يَا أَيُّهَا الْكَافِرُونَ(Say: "O Al-Kafirun!'') and قُلْ هُوَ اللَّهُ أَحَدٌٌ (Say: "He is Allah One.'') (Surah: 112))."
Ahmad recorded that Ibn `Umar said,
"I watched the Prophet for a month and he would recite in the two Rakahs before the Morning prayer, قُلْ يَا أَيُّهَا الْكَافِرُونَ (Say: "O Al-Kafirun!'') and قُلْ هُوَ اللَّهُ أَحَدٌ (Say: " He is Allah One.'' (Surah: 112)).
This was also recorded by At-Tirmidhi, Ibn Majah and An-Nasa'i.
At-Tirmidhi said, "Hasan.''
It has already been mentioned previously in a Hadith that it (Surah Al-Kafirun) is equivalent to a fourth of the Qur'an and Az-Zalzalah is equivalent to a fourth of the Qur'an.
