The Book of Faith
Ṣaḥīḥ Muslim 126
لاَ إِلَهَ إِلاَّ اللَّهُ وَيُؤْمِنُوا بِي وَبِمَا جِئْتُ بِهِ فَإِذَا فَعَلُوا ذَلِكَ عَصَمُوا مِنِّي دِمَاءَهُمْ وَأَمْوَالَهُمْ إِلاَّ بِحَقِّهَا وَحِسَابُهُمْ عَلَى اللَّهِ
lā ilaha illā-Llāh wayuʾminūā bī wabimā jiʾtu bihi fa-idhā faʿalūā dhalika ʿaṣamūā minnī dimāʾahum wa-amwālahum illā biḥaqqihā waḥisābuhum ʿalā-Llāh

The full narration
It is reported on the authority of Abu Huraira that he heard the Messenger of Allah say:I have been commanded to fight against people, till they testify to the fact that there is no god but Allah, and believe in me (that) I am the messenger (from the Lord) and in all that I have brought. And when they do it, their blood and riches are guaranteed protection on my behalf except where it is justified by law, and their affairs rest with Allah
