The Fitrah Proves the Existence of Allah

When faced with calamities, man instinctively says, "O Allah." We are told that when an unexpected harm befalls, even some disbelievers and atheists - due to slip of the tongue and without realizing – say, "O Allah."

This occurs because the  Fitrah  of man  testifies to the  Existence  of Allah, "(Remember) when your Lord brought forth from the Children of Adam, from  their  loins, their  seed  and  made  them  testify  as to themselves (saying),  "Am I not  your  Lord?"  They said, "Yes! We testify." [Surah al-A'raf (7): 172]

Shaikh Fawzan writes in Aqeedah at-Tawheed,

"Firawn - who is famous for his pretense of denying the (existence of) Lord, was convinced about it inwardly, as Moosa said to him, "Verily you know that these signs have been sent down by none but the Lord of the heavens and the earth as clear (evidences)." [Surah al-Isra’ (17): 102]

Allah said  about Fir'awn  and  his people,  "they  belied  them  (those Ayaat)  wrongfully and  arrogantly, though their  own  selves  were convinced thereof." [Surah an-Naml (27): 14]

Similarly, today the denial of the atheist is also superficial and out of stubbornness. Otherwise, they surely affirm within themselves that there is nothing that exists except that it has an originator. There is no creation except that it has a creator. There is no trace except that it has someone who formed that trace. He, the Exalted, says, "Were they created by nothing, or were they themselves the creators? Or did they create the heavens and the earth? Nay, but they have no firm belief." [Surah at-Toor (52): 35-36]

Consider all parts of this world, you will find it testifying to the existence of its Originator, Creator and Owner.

Denial and rejection of a Creator is like denying and rejecting knowledge - No difference. (Because the correct knowledge proves the existence of the Creator).

The atheist who boast about their denial of the Lord's existence, do so out of pride and lack of sound intellect and ideologies. He who is like them has revoked his intelligence and invited people to scoff at him. As the poet says:

“How can Allah be disobeyed and rejected by the jahid (the denier), (while) in everything, there is a sign which points out that he is Waahid (One).”
