Faith in Islam is not blind – it is based upon evidence and logic. Not seeing something does not imply its nonexistence. For instance, no one has ever seen their great, great, great, great, great, great, great, great, great, great grandmother since any observable evidence of her existence cannot be found – this includes her grave, her DNA, etc. Yet, no logical person descended from her could deny that she had existed.

In Islam, faith has six articles which are:

Believing in Allah, His Angels, His Books, His Messengers, The Last Day, and The Divine Decree [the good, and what we erroneously perceive as bad].

It is required to believe and affirm all of these articles of faith as a Muslim.

Sheikh Muhammad Ibn Saleh Al-Uthaymeen said:
“Islam, as we explained before, is belief and Laws. We mentioned some pillars of the Laws. These pillars are the basis of Islamic Law. As for the Islamic ‘Aqeedah (creed), its pillars are: Believing in Allah, His Angels, His Books, His Messengers, the Last Day and the good or bad that Qadar (predestination) brings. These pillars are mentioned in the Book of Allah and the Sunnah of His Messenger (sallallahu alaihi wa-sallam).

Allah said, what translated means, “Righteousness is not that you (only) turn your faces towards the East and (or) the West (in prayers); but righteousness is (the quality) of the one who believes in Allah, the Last Day, the Angels, the Book and the Prophets” [2:177], and with regards to Qadar, “Verily, We have created all things with Qadar. And Our Commandment is but one, as the twinkling of an eye.” [54:49].

In the Sunnah, the Messenger of Allah said, in answer to Gibreel when he asked him about Iman (belief), “Iman is to believe in Allah, His Angels, His Books, His Messengers, the Last Day, and to believe in the Qadar and what it brings of good or bad.” [ Saheeh Muslim]”
