How do we know Allah?

It is again the perfect creation throughout the universe that introduces to us the supreme power of Allah. However, Allah has principally introduced Himself to us in the Quran, which He has sent down to people as a guide to right living. In the Quran, all the supreme qualities of Allah, His wisdom, knowledge, compassion, mercy, justice, omnipresence, His seeing and hearing everything, His being the sole owner and sole God of the Heavens, the Earth and all that lies between and His being the sole sovereign of the kingdom are conveyed to us.

He is Allah – there is no god but Him. He is the Knower of the Unseen and the Visible. He is the Compassionate and Most Merciful. He is Allah – there is no god but Him. He is the King, the Most Pure, the Perfect Giver of Peace, the Trustworthy, the Safeguarder, the Almighty, the Compeller, the Supremely Great. May Allah be exalted above all they associate with Him. He is Allah – the Creator, the Maker, the Giver of Form. To Him belong the Most Beautiful Names. Everything in the heavens and earth glorifies Him. He is the Almighty, the All-Wise. (Surat al-Hashr: 22-24)
