If anyone says "I am pleased with Allah as Lord, with Islam as religion and with Muhammad ﷺ as Apostle" Paradise will be his due. (Using translation from Abū Dāʾūd 1529)
سَمِعْتُ أَبَا عَلِيٍّ الْجَنْبِيُّ قَالَ سَمِعْتُ أَبَا سَعِيدٍ الْخُدْرِيَّ يَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ مَنْ قَالَ رَضِيتُ بِاللَّهِ رَبًّا وَبِالْإِسْلَامِ دِينًا وَبِمُحَمَّدٍ رَسُولًا وَجَبَتْ لَهُ الْجَنَّةُ
