Who believe in the Ghaib ^[] and perform As-Salât (Iqâmat-as-Salât), ^[] and spend out of what we have provided for them [i.e. give Zakât ^[], spend on themselves, their parents, their children, their wives, etc., and also give charity to the poor and also in Allâh's Cause - Jihâd, etc.]. (2:3)

"Who believe in the Ghaib (unseen)"

What is Ghaib (unseen)?

As we see in the morning the sun rises, continues for the entire day until it sets in the evening. Daily we see the sun being born in the morning, and it's gone in the evening, however the sun is still there, but it is dark for the rest of the night. 

There are many examples about the things which are hidden such as gravity, which no one can see, however its force is there. Or lets look at ourselves, if anyone talks to someone else, the words of one person to the next, they both can hear each other, however it cannot be seen. If one is looking at something, the beam of that person's eyesight cannot be seen, but he can tell you what he is focusing on, the same thing applies to someone thinking about something, however what that person is thinking cannot be seen, while thinking is the most important function of the brain, when we hear and see, our brain records it, then  stores it in our memory, it's then used whenever its required, right away, a month, or even years after. When a portion of the body is in pain, that person who is suffering will complain to you, but no one can see his suffering, or if one is hungry, it cannot be seen, but that person will tell you he is hungry, and many more examples one can start to think, when understanding the unseen. 

Now we should see our soul is unseen, when the mother receives life in her fetus, she has no idea about it, but only she can feel it's movement. And when the life leaves a body, the body looks fine, but you can tell that person is dead, and no one can see the soul actually leaving.

All unseen things are reality, this explains why Allah, his angels, soul, and Satan are all unseen things, but a reality. 

 "and perform As-Salât (Iqâmat-as-Salât),"

Salah is one the most important and highest action in worshipping one's creator. This is the only best way to communicate with one's creator, and the system of prayer (salah) is taught to us by our creator.

"and spend out of what we have provided for them [i.e. give Zakât ^[], spend on themselves, their parents, their children, their wives, etc., and also give charity to the poor and also in Allâh's Cause - Jihâd, etc.]."

^{One may ask what is the purpose of giving charity?}

^{All our luxuries, status, and benefits are only from Allah our provider. Whatever we claim to own is only in our head because, once we die, we cannot take it with us, regardless if we leave behind billions. Each and every cent given to us is given by Allah, we are only trustees of it from Allah, and its users.}

^{And the real owner for everything is Allah, zakat (charity) is a test from Allah to those who certify themselves to be Muslims, obedient and worshippers of Allah. How can they take out only a 2.5% of there yearly earnings towards the needy, however one can give as much as he wants to, in order to earn Allah's favor upon us.}
