حَدَّثَنَا أَبُو سَعِيدٍ الأَشَجُّ ، حَدَّثَنَا عُقْبَةُ بْنُ خَالِدٍ ، عَنْ أَبِي سَعْدٍ، سَعِيدِ بْنِ الْمَرْزُبَانِ عَنْ أَبِي سَلَمَةَ ، عَنْ ثَوْبَانَ ، رضى الله عنه قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ قَالَ حِينَ يُمْسِي رَضِيتُ بِاللَّهِ رَبًّا وَبِالإِسْلاَمِ دِينًا وَبِمُحَمَّدٍ نَبِيًّا كَانَ حَقًّا عَلَى اللَّهِ أَنْ يُرْضِيَهُ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ مِنْ هَذَا الْوَجْهِ .
“The Messenger of Allah (ﷺ) said: ‘Whoever says when he reaches the evening: “I am pleased with Allah as (my) Lord, with Islam as (my) religion, and with Muhammad (ﷺ) as (my) Prophet (Raḍītu billāhi rabban wabil-Islāmi dīnan wa bi-Muḥammadin nabiyyan) it is a duty upon Allah to please him.’” (Hasan Gharib)
