Belief In Allah’s Existence is affirmed through Fitrah (the innate purity that Allah creates in every human being), the Mind, the Shari’ah (Islamic Law) and the senses.
a) As for the Fitrah, we say the following: Allah created the belief in Him in every human being. Mankind needs not to be taught this belief or think about how to possess it. However, the ones who have this Fitrah corrupted will not benefit from it. The Prophet (sallallahu alaihi wa-sallam) said, what translated means, "Every newly born will be born having Fitrah. However, his parents will either convert him to Judaism, Christianity or Majocism (fire worshipping)." [Saheeh al-Bukhari]
«ما من مولود إلا يولد على الفطرة، فأبواه يهودانه، أو ينصرانه، أو يمجسانه»
صحيح البخاري
b) The Human Mind must be used to prove the existence of Allah. All this creation, of old and new, must have a Creator who invented and started it. This creation could not have come to existence on its own or by chance. It could not have created itself, because it did not exist beforehand. Therefore, how can it create? Also, the creation could not have been started by accident or chance. Everything that exists must have a Creator who brought it into existence. Creation is magnificent in organization, coherent and correlated in its existence. There is a reason and originator behind every act. All this nullifies the saying that this entire universe was started by chance. What was started by chance cannot be organized in its form because it did not have any organization before it was formed. What makes what was created by chance to be this organized? If all this creation neither could have created itself nor was it created by chance, then it must have an Originator, Allah, the Lord of the worlds. Allah mentioned this reasoning in the Quran, "Were they created by nothing, or were they themselves the creators?" [At-Tur52:35]
{أَمْ خُلِقُوا مِنْ غَيْرِ شَيْءٍ أَمْ هُمُ الْخَالِقُونَ}
الطور: 35
Transliteration: Am khuliqoo min ghayri shayin am humu alkhaliqoona
Jubair, a disbeliever then, said, "My heart almost flew (from the power of this reasoning mentioned in the Surah). This was the first time that Iman entered my heart." [Saheeh al-Bukhari]
«سمعت النبي صلى الله عليه وسلم يقرأ في المغرب بالطور ، وذلك أول ما وقر الإيمان في قلبي.»
صحيح البخاري
c) - As for the Shari'ah, all divine religions testify to the fact that Allah created the world. All Laws that were sent with these divine and revealed religions contain what benefits mankind. This is evidence to the existence of a Wise and All-Knowing Lord Who knows what brings benefit to His creation, All divinely-revealed religions describe a universe that is self evident to the existence and ability of Allah, Who Creates what He Will.
Belief In Allah's Lordship This means to believe that Allah is the Lord, alone, and that He has no partners or helpers. The Rabb (Lord) is the One who Creates and Commands. There is no creator except Allah and there is no owner of the universe except Him. The Commandment and the Control is His. He said, what translated means, "Surely, His is the Creation and commandment." [Al-A'raaf 7:54]
