The Messenger of Allah (pbuh) is quoted saying, "Whoever recites al-Tkhlas will be as though he has recited one third of the Holy Qur’an and will be granted ten good deeds for each and everyone who believed in Allah, His angels, His books, His messengers, and the Day of Judgement ." He (pbuh) has also said, "If someone recites it once, he will be blessed; if he recites it twice, he and his family will be blessed." Imam Ali ibn Abu Talib (as) has said, "‘Whoever recites it eleven times after fajr prayers will be safeguarded against committing any sin that day despite Satan’s nose." AI-Bataini quotes Sayf ibn ‘Ameerah quoting Abu Bakr al-iladrami quoting Abu Abdullah Imam al-Sadiq (as) saying, "Whoever believes in Allah and the Last Day ought to recite Surat al-lkhlas after each obligatory prayer, for whoever recites it will gain the good of this life and the life to come, and Allah will forgive him, his parents, and their offspring." One particular incident related by al-Majlisi with reference to this great Chapter is worth quoting here as narrated by Anas, a companion of the Prophet (pbuh), thus: We were once in the company of the Messenger of Allah (pbuh) at Tabuk.

The sun rose one day with rays and light the like of which we had never seen before. The Messenger of Allah (pbuh) kept wondering about its light and rays.

Suddenly Gabriel (as) came tp him, so he (pbuh) asked him, "What is with the sun, O Gabriel, and what is with its light and illumination and rays which I have never seen before?" Gabriel (as) said, "This is due to Mu’awiyah ibn Mu ‘awiyah al-Laythi (al-Mazni) who died today in Medina; so Allah sent seventy thousand angels to perform the prayers on his soul." "What for?" asked the Prophet (pbuh).
