Abu Dharr narrated that:

The Messenger of Alah said: “Whoever says at the end of every Fajr prayer, while his feet are still folded, before speaking: ‘None has the right to be worshipped but Allah, Alone without partner, to Him belongs all that exists, and to Him is the praise, He gives life and causes death, and He is powerful over all things, (La Ilaha Illallah, Wahdahu La Sharika Lahu, Lahul-Mulku Wa Lahul-Hamdu, Yuhyi Wa Yumitu, Wa Huwa Ala Kulli Shai’in Qadir)’ ten times, then ten good deeds shall be written for him, ten evil deeds shall be wiped away from him, ten degrees shall be raised up for him, and he shall be in security all that day from every disliked thing, and he shall be in protection from Shaitan, and no sin will meet him or destroy him that day, except for associating partners with Allah.”
