Those who seek the truth sincerely must believe in Allah and His Last Prophet Muhammad and utter this testimony: I testify that there is no god but Allah, and I testify that Muhammad is the messenger of Allah.” In Arabic, “ASH-HADU ALLA ILAHA ILLALLAH, WA ASH-HADU ANNA MUHAMMADAN RASULULLAH.”
Prophet Muhammad explained to us the five pillars of Islam: Shahadah (the testimony), Salat (prayer), Zakat (charity), Sawm (fasting), and Hajj (pilgrimage).
Muhammad taught us the six articles of Islam: Belief in Allah (the one true God), His angels, His revelations, His Messengers, the Last Day, and destiny.
Allah sent Muhammad as a mercy to all mankind.
Muslims follow the commandments that Muhammad, Jesus, and Moses taught and did, like believing in one God, praying, fasting, and giving charity.
Muhammad, Jesus, and Moses used to say ‘Insha Allah’ (if God wills), and using the greeting: ‘Asalamu Alaikum’ ( Peace be upon you)!
