The Messenger of Allah ﷺ said, "Whoever says after the dawn prayer, 'There is no god but Allah alone, with no partner. To Him belongs the dominion and to Him belongs all praise, and He is capable of all things,' ten times, it counts for him as the equivalent of freeing four slaves. Ten good deeds are recorded for him, ten sins are wiped away from him, he is raised by ten degrees, and the words guard him from Satan until evening. And when he says them after the sunset prayer, he receives the same."
حدثنا إسحاق بن إبراهيم الرازي حدثنا سلمة بن الفضل حدثني محمد بن إسحاق عن يزيد بن يزيد بن جابر عن القاسم بن مخيمرة عن عبد الله بن يعيش
قال رسول الله ﷺ من قال إذا صلى الصبح لا إله إلا الله وحده لا شريك له له الملك وله الحمد وهو على كل شيء قدير عشر مرات كن كعدل أربع رقاب وكتب له بهن عشر حسنات ومحي عنه بهن عشر سيئات ورفع له بهن عشر درجات وكن له حرسا من الشيطان حتى يمسي وإذا قالها بعد المغرب فمثل ذلك
Its isnad is sahih. Yazid bin Yazid bin Jabir is the jurist from Damascus. Qasim bin Mukhaymara al-Shami is trustworthy and among the most excellent. Abdullah bin Yaish was mentioned by Ibn Hibban among the trustworthy, though some, such as Husayni and Ibn Jawzi, did not know him. The hadith has already appeared at 23408.
