AHMAD 18199:
from ʿAbdah And ʿAbd al-Malik —
[Machine] "We heard that a man-Warraq wrote to him, meaning Al-Mughirah, and Mu'awiyah wrote to him, saying, 'Write to me about something you heard from the Messenger of Allah ﷺ.' So, Al-Mughirah wrote to him, meaning Mu'awiyah, 'Verily, the Messenger of Allah ﷺ used to say, "There is no god but Allah alone, without partner. His is the kingdom, and His is the praise, and He is capable of all things."'

عن عبده و عبد الملك —
سَمِعْنَا وَرَّادًا كَتَبَ إِلَيْهِ يَعْنِي الْمُغِيرَةَ كَتَبَ إِلَيْهِ مُعَاوِيَةُ اكْتُبْ إِلَيَّ بِشَيْءٍ سَمِعْتَهُ مِنْ رَسُولِ اللهِ ﷺ فَكَتَبَ إِلَيْهِ يَعْنِي الْمُغِيرَةَ إِنَّ رَسُولَ اللهِ ﷺ كَانَ يَقُولُ لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ
