«وَإِنَّ صَلَّى وَصَامَ وَزَعَمَ أَنَّهُ مُسْلِمٌ، فَادْعُوا الْمُسْلِمِينَ بِأَسْمَائِهِمْ عَلَى مَا سَمَّاهُمُ اللهُ عَزَّ وَجَلَّ الْمُسْلِمِينَ الْمُؤْمِنِينَ عِبَادَ الله»
(And I order you with five commandments that Allah has ordered me. Stick to the Jama`ah (community of the faithful), listen and obey (your leaders) and perform Hijrah (migration) and Jihad for the sake of Allah. Whoever abandons the Jama`ah, even the distance of a hand span, will have removed the tie of Islam from his neck, unless he returns. Whoever uses the slogans of Jahiliyah (the pre-Islamic period of ignorance) he will be among those kneeling in Jahannam (Hellfire).) They said, â€O Messenger of Allah! Even if he prays and fasts'' He said, (Even if he prays, fasts and claims to be Muslim. So call the Muslims with their names that Allah has called them: `The Muslims, the believing servants of Allah.') This is a Hasan Hadith, and it contains the statement, â€Allah has created and sustains you, so worship Him and do not associate anything with Him in worship.'' This statement is relevant in the Ayat (2:21-22) we are discussing here and supports singling Allah in worship, without partners.  Several scholars of Tafsir, like Ar-Razi and others, used these Ayat as an argument for the existence of the Creator, and it is a most worthy method of argument. Indeed, whoever ponders over the things that exist, the higher and lower creatures, their various shapes, colors, behavior, benefits and ecological roles, then he will realize the ability, wisdom, knowledge, perfection and majesty of their Creator. Once a bedouin was asked about the evidence to Allah's existence, he responded, â€All praise is due to Allah! The camel's dung testifies to the existence of the camel, and the track testifies to the fact that someone was walking. A sky that holds the giant stars, a land that has fairways and a sea that has waves, does not all of this testify that the Most Kind, Most Knowledgeable exists'' Hence, whoever gazes at the sky in its immensity, its expanse, and the various kinds of planets in it, some of which appear stationary in the sky - whoever gazes at the seas that surround the land from all sides, and the mountains that were placed on the earth to stabilize it, so that whoever lives on land, whatever their shape and color, are able to live and thrive - whoever reads Allah's statement,
