Abdullah bin Abbas reported,

The Prophet ﷺ said, "All praise belongs to Allah. We praise Him and seek His help. Whoever Allah guides, none can lead astray, and whoever He leaves astray, none can guide. I bear witness that there is no god but Allah alone, with no partner, and that Muhammad is His servant and messenger. Now to proceed."

Sahih

عن ابن عباس

أن النبي ﷺ قال: إن الحمد لله نحمده ونستعينه، من يهده الله فلا مضل له، ومن يضلل فلا هادي له، وأشهد أن لا إله إلا الله وحده لا شريك له، وأن محمدا عبده ورسوله، أما بعد.
