Lesson 10 - The Pillars of Islam (Part 10) - The second part of the shahadah - to testify that the Prophet ﷺ is the servant and messenger of Allah. This implies that you only worship Allah with what the Prophet ﷺ came with and that not doing so constitutes innovation in the religion.
Also that the entire deen is established upon the two parts of the shahadah - laa ilaaha illa Allah is sincerity in worship, and Muhammad rasoolo Allah is conformity in worship. Allah will only accept good deeds if they are sincerely for His sake and performed according to the Sunnah of the Prophet ﷺ.
