Reciting Ayat-ul-Kursy and Al-Mu`awwidhatayn

A: It is Sunnah (supererogatory act of worship following the example of the Prophet) to recite Ayat-ul-Kursy, Surah Al-Ikhlas, and A-Mu`awwidhatayn in a subvocal voice after finishing reciting the Adhkar (invocations and remembrances said at certain times on a regular basis) prescribed to be said after Taslim (salutation of peace ending the Prayer). This is based on the Hadith related by Al-Nasa'y, which Ibn Hibban ranked as Sahih (authentic), on the authority of Abu Umamah Iyas ibn Tha`labah Al-Harithy Al-Ansary Al-Khazrajy who narrated that the Messenger of Allah (peace be upon him) said: Anyone who recites Ayat-ul-Kursy after every obligatory Salah will have nothing to stand between them and entering Paradise except death. Imam Ahmad and other scholars also related on the authority of Abu Umamah that the Messenger of Allah (peace be upon him) used to recite Ayat-ul-Kursy in a subvocal voice after every Salah. This Hadith is ranked as Sahih in Al-Mukhtarah. Al-Tabarany added (Surah Al-Ikhlas): Say (O Muhammad صلى الله عليه وسلم): "He is Allâh, (the) One. Ibn Al-Qayyim said that there are lines of transmissions that indicate that this Hadith has an origin (to support it). Further on this subject, Abu Dawud, Al-Tirmidhy, Al-Nasa'y, and others related on the authority of `Uqbah ibn `Amir (may Allah be pleased with him) that he said: The Messenger of Allah (peace be upon him) ordered me to recite Al-Mu`awwidhatayn directly after every Salah. According to the narration of Abu Dawud: "...The Mu`awwidhat i.e. (Surahs Al-Falaq, Al-Nas and Al-Ikhlas)." (Part No. 7; Page No. 109)
