Is reciting Surat Al-Kafiroon and Surat Al-Ikhlas in the two Sunnah rak'ahs of Fajr and Maghrib desirable and a Sunnah from the Messenger of Allah, peace and blessings be upon him?

It is recommended to recite Surahs "Al-Kafirun" and "Al-Ikhlas" in the Sunnah prayer of Fajr and the Sunnah prayer of Maghrib, following the example of the Prophet, peace and blessings be upon him, as established in the authentic Sunnah.

The reason for the recommendation to recite them is that they encompass the three types of Tawhid (Oneness of God): Surah "Al-Ikhlas" includes Tawhid al-Rububiyyah (Oneness of Lordship) and Tawhid al-Asma wa al-Sifat (Oneness of Names and Attributes). Surah "Al-Kafirun" contains Tawhid al-Ibadah (Oneness of Worship).

Therefore, the Prophet, peace and blessings be upon him, commenced the day with them in the Sunnah of Fajr and concluded with them in the Sunnah of Maghrib, and he also used to recite them in his Witr prayer, thus making them the conclusion of the deeds of the night and day.
