The Messenger of Allah ﷺ said: If anyone says in the morning: "There is no god but Allah alone Who has no partner; to Him belong the dominions, to Him praise is due, and He is Omnipotent," he will have a reward equivalent to that for setting free a slave from among the descendants of Isma'il. He will have ten good deeds recorded for him, ten evil deeds deducted from him, he will be advanced ten degrees, and will be guarded from the Devil till the evening. If he says them in the evening, he will have a similar recompense till the morning. The version of Hammad says: A man saw the Messenger of Allah ﷺ in a dream and said: Messenger of Allah! AbuAyyash is relating such and such on your authority. He said: AbuAyyash has spoken the truth. Abu Dawud said: Isma'il b. Ja'far, Musa al-Zim'i and 'Adb Allah b. Ja'far transmitted it from Suhail, from his father on the authority of Ibn 'A'ish. (Using translation from Abū Dāʾūd 5077)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «مَنْ قَالَ لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوعَلَى كُلِّ شَيْءٍ قَدِيرٌ كَانَتْ لَهُ كَعِتْقِ رَقَبَةٍ مِنْ وَلَدِ إِسْمَاعِيلَ وَكُتِبَ لَهُ عَشَرُ حَسَنَاتٍ وَحُطَّ عَنْهُ عَشَرُ سَيِّئَاتٍ وَرُفِعَ لَهُ عَشَرُ دَرَجَاتٍ وَكَانَ فِي حِرْزٍ مِنَ الشَّيْطَانِ حَتَّى يُمْسِيَ فَإِنْ قَالَهَا إِذَا أَمْسَى كَانَ لَهُ مِثْلُ ذَلِكَ» قَالَ فَرَأَى رَجُلٌ رَسُولَ اللهِ ﷺ فِيمَا يَرَى النَّائِمُ فَقَالَ يَا رَسُولَ اللهِ إِنَّ أَبَا عَيَّاشٍ الزُّرَقِيِّ أَخْبَرَنَا عَنْكَ بِكَذَا وَكَذَا فَقَالَ النَّبِيُّ ﷺ «صَدَقَ أَبُو عَيَّاشٍ»
