AbuSallam told that he was in the mosque of Hims. A man passed him and the people said about him that he served the Prophet ﷺ. He (AbuSallam) went to him and said: Tell me any tradition which you heard from the Messenger of Allah ﷺ and there were no man between him and you. He said: I heard the Messenger of Allah ﷺ say: If anyone says in the morning and in the evening: "I am pleased with Allah as Lord, with Islam as religion, with Muhammad as Prophet," Allah will certainly please him. (Using translation from Abū Dāʾūd 5072)
مَرَّ رَجُلٌ فِي مَسْجِدِ حِمْصَ فَقَالُوا هَذَا خَادِمُ النَّبِيِّ ﷺ قَالَ فَقُمْتُ إِلَيْهِ فَقُلْتُ حَدِّثْنِي حَدِيثًا سَمِعْتَهُ مِنْ رَسُولِ اللهِ ﷺ لَا يَتَدَاوَلُهُ بَيْنَكَ وَبَيْنَهُ الرِّجَالُ قَالَ قَالَ رَسُولُ اللهِ ﷺ مَا مِنْ عَبْدٍ مُسْلِمٍ يَقُولُ حِينَ يُصْبِحُ وَحِينَ يُمْسِي ثَلَاثَ مَرَّاتٍ رَضِيتُ بِاللهِ رَبًّا وَبِالْإِسْلَامِ دِينًا وَبِمُحَمَّدٍ ﷺ نَبِيًّا إِلَّا كَانَ حَقًّا عَلَى اللهِ أَنْ يُرْضِيَهُ يَوْمَ الْقِيَامَةِ
