Worshipping Allah is accepted only from the believers. The believers believe in the existence of Allah, and do not liken Him to any of His creations. Suratush-Shura, Ayah 11 means, “Nothing is like Allah in any way.” The Prophet, sallallahu ^alayhi wa sallam, said, “Do not attempt to imagine the Self of Allah” (Related by Abul-Qasim Al-Ansariyy). The scholar Al-Ghazaliyy said, “Worship is valid only after one has correct knowledge and belief in the One Who deserves to be worshipped [Allah].”
