It is not too difficult to be a practising Muslim.
1. Believe in One, Unique, Incomparable God (Allah); in the Angels created by Him; in the prophets through whom His revelations were brought to mankind; in the Day of Judgement and individual accountability for actions; in God's complete authority over human destiny and in life after death.
2. Profess faith that the only God is Allah, while Muhammad is His Messenger. Perform the Prayer. Set aside the 'Zakat' (Alms for the poor) from one's capital. Fast during the month of Ramadan. And for those who can afford it, perform the Pilgrimage (Hajj) to Makkah.
3. Be sincere (Ikhlas) in performing all the above. Do not show-off to anybody save to Allah.
