Musnad Ahmad 341:0

Narrated Abu Ayyash al-Zuraqi: The Messenger of Allah (ﷺ) said: "Whoever says in the morning: 'There is no god but Allah alone, He has no partner; to Him belongs the dominion, and to Him belongs the praise, and He is powerful over all things' (La ilaha illallah wahdahu la sharika lah, lahul-mulku wa lahul-hamdu wa huwa 'ala kulli shay'in qadir), it will be for him the equivalent of freeing a slave from the children of Ismail. He will have ten good deeds written for him, ten bad deeds will be erased from him, he will be raised ten degrees, and he will be in a shelter from Satan until the evening. And if he says it in the evening, he will have the same until the morning."
