The Prophet ﷺ said, "Whoever says in the morning, 'There is no god but Allah alone, with no partner. To Him belongs the kingdom and to Him belongs all praise. He gives life and causes death, and He has power over all things,' ten times, Allah will record for him ten good deeds for each time he says it, will erase from him ten bad deeds, will raise him by them ten ranks, and they will be for him equivalent to freeing ten slaves. They will be a protection for him from the beginning of the day until its end, and he will not perform on that day any deed that overcomes them. If he says it when he reaches the evening, the same applies."
عن النبي ﷺ أنه قال: من قال حين يصبح: لا إله إلا الله وحده، لا شريك له، له الملك وله الحمد، يحيي ويميت وهو على كل شيء قدير، عشر مرات، كتب الله له بكل واحدة قالها عشر حسنات، وحط الله عنه بها عشر سيئات، ورفعه الله بها عشر درجات، وكن له كعشر رقاب، وكن له مسلحة من أول النهار إلى آخره، ولم يعمل يومئذ عملا يقهرهن، فإن قال حين يمسي، فمثل ذلك.
Ahmad narrated it (23568), and Tabarani in Al-Kabir (4/151), both through the route of Ismail bin Ayyash, from Safwan bin Amr, from Khalid bin Madan, from Abu Rahm Sunabihi, from Abu Ayub Ansari, who related it.Its chain of transmission is hasan because of Ismail bin Ayyash, for his hadith is hasan when he narrates from the people of Syria, and this narration is one of those. Abu Rahm Sunabihi is Ahzab bin Usayd, one of the reliable narrators among the mukhadramun.
