Hadith 8163

وَبِإِسْنَادِهِ ، وَبِإِسْنَادِهِ ، قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " لَا أَزَالُ أُقَاتِلُ النَّاسَ حَتَّى يَقُولُوا : لَا إِلَهَ إِلَّا اللَّهُ ، فَإِذَا قَالُوا : لَا إِلَهَ إِلَّا اللَّهُ ، فَقَدْ عَصَمُوا مِنِّي أَمْوَالَهُمْ وَأَنْفُسَهُمْ إِلَّا بِحَقِّهَا ، وَحِسَابُهُمْ عَلَى اللَّهِ عَزَّ وَجَلَّ " .
And the Noble Prophet (peace and blessings be upon him) said: I will continue to fight against the people until they declare that there is no god but Allah. When they recite this statement, then know that they have protected their lives and wealth from me, except for its due right, and their reckoning is with Allah.
