The Messenger of Allah ﷺ said, "Whoever says in the morning, 'There is no god but Allah alone, with no partner. To Him belongs the dominion and to Him belongs all praise, and He has power over all things,' it will be equivalent to freeing a slave from the descendants of Ismail. Ten good deeds will be recorded for him, ten sins will be wiped away from him, he will be raised ten degrees, and he will be in the protection of Allah from Satan until evening. If he says it in the evening, he will have the same until morning."A man saw the Messenger of Allah ﷺ in a dream and said, "Messenger of Allah, Abu Ayyash narrates such and such from you."He replied, "Abu Ayyash has spoken the truth."
قال رسول الله ﷺ: من قال إذا أصبح: لا إله إلا الله وحده لا شريك له له الملك وله الحمد وهو على كل شيء قدير، كان له عدل رقبة من ولد إسماعيل، وكتب له عشر حسنات، وحط عنه عشر سيئات، ورفع له عشر درجات، وكان في حرز من الشيطان حتى يمسي، وإن قالها إذا أمسى كان له مثل ذلك حتى يصبح. قال: فرأى رجل رسول الله ﷺ فيما يرى النائم فقال: يا رسول الله إن أبا عياش يحدث عنك بكذا وكذا قال: صدق أبو عياش
It was narrated by Abu Dawud (5077), Ibn Majah (3867), Nasai in Amal al-Yawm wal-Layla (27), and Ahmad (16583), all of them through Hammad bin Salama, from Suhayl bin Abu Salih, from his father, from Abu Ayyash Zurqi, who mentioned it. Its chain of transmission is sahih, and it has other chains as well.There is disagreement over the name of the companion. Some said Abu Ayyash, others said Ibn Abu Ayish, and others said Ibn Ayish. This does not undermine the soundness of the chain of transmission.
