What proves that Islam is the last and most suitable religion? What are the religious practices, such as zakat, that have changed from previous religions to Islam? What are the sources of distortion in Christianity and Judaism, and what is the meaning of the rule of the Trinity?

The Seal of the Prophets is Muhammad, peace be upon him. The Quran is the greatest reference, and Islam is the only religion acceptable to Allah. Legitimate acts of worship from previous religions that continue in Islam include: Hajj, charity, remembrance [of Allah], and supplication. Yahya ibn Zakariyya (John the Baptist), peace be upon him, was commanded by Allah with five words: not to associate anything with Allah, to establish prayer without turning away, fasting, charity, and frequent remembrance of Allah. Allah commanded Muhammad, peace be upon him, with five: congregational prayer, listening, obedience, emigration (Hijra), and striving (Jihad) in the way of Allah.
