Three things to be content with
The consequence attached to it is unusually short.
مَنْ قَالَ رَضِيتُ بِاللَّهِ رَبًّا وَبِالإِسْلاَمِ دِينًا وَبِمُحَمَّدٍ رَسُولاً وَجَبَتْ لَهُ الْجَنَّةُ
Man qāla: raḍītu bi-Llāhi rabban wa bi-l-islāmi dīnan wa bi-Muḥammadin rasūlā, wajabat lahu-l-jannah
“Whoever says: I am pleased with Allah as Lord, with Islam as religion, and with Muhammad as Messenger, Paradise becomes due for him.”
Where this comes from
Wajabat is a word from contracts. It means the thing has fallen due, become owed. Not hoped for. Not likely. Owed.
The full narration
Abu Sa'id al-Khudri reported the Messenger of Allah (ﷺ) as saying: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
