The 5 pillars of Islam are the most fundamental commands from Allah for us to follow. Without doing these, you aren't a true Muslim (Though Hajj is excused from people who can't afford it). Here they are:

Like we mentioned earlier, the people who are only excused are the ones who can't afford it. One of the fundamental principles of Islamic Spirituality is the Principle of Unity, derived from tawheed — oneness.

“All men are equal before God as are the teeth of a comb.”
— Prophet Muhammad (saws)
