The meaning of Islam is to surrender all of your "buts" and "why", and to submit to the will of your creator, and whatever is said by Allah, then to accept all of your movements and speech to, and all of our charity to the will of Allah.

And to accept the five pillars of Islam:

ALLAH

(To witness and understand Allah and his Prophet (SAW)

PRAYERS

(To pray five times a day)

ZAKAH

(To pay Zakah (charity)

RAMADAN

(To fast in the month of Ramadan)

HAJJ

(To pilgrimage to be performed at least once in a lifetime)

And the six pillars of iman

BELIEF IN ALLAH
HIS ANGELS
HIS BOOKS
HIS PROPHETS
AND ON THE DAY OF JUDGEMENT
AND IN DIVING PREORDAINEMENT, MEANING THAT GOOD AND BAD IS ONLY FROM ALLAH, AND LIFE AFTER DEATH
