(11) بَاب الدَّلِيلِ عَلَى أَنَّ مَنْ رَضِيَ بِاللَّهِ رَبًّا وَبِالْإِسْلَامِ دِينًا وَبِمُحَمَّدٍ رَسُولًا فَهُوَ مُؤْمِنٌ وَإِنْ ارْتَكَبَ الْمَعَاصِيَ الْكَبَائِرَ

He has found the taste of faith (iman) who is content with Allah as his Lord, with Islam as his religion (code of life) and with Muhammad (ﷺ) as his Prophet. (RU)
