: Say (O Muhammad SAW): "To whom belongs all that is in the heavens and the earth?" Say: "To Allah. He has prescribed Mercy for Himself. Indeed He will gather you together on the Day of Resurrection, about which there is no doubt. Those who destroy themselves will not believe [in Allah as being the only Ilah (God), and Muhammad SAW as being one of His Messengers, and in Resurrection, etc.].
: Say (O Muhammad SAW): "Shall I take as a Wali (helper, protector, etc.) any other than Allah, the Creator of the heavens and the earth? And it is He Who feeds but is not fed." Say: "Verily, I am commanded to be the first of those who submit themselves to Allah (as Muslims)." And be not you (O Muhammad SAW) of the Mushrikun [polytheists, pagans, idolaters and disbelievers in the Oneness of Allah].
: Say (O Muhammad SAW): "What thing is the most great in witness?" Say: "Allah (the Most Great!) is Witness between me and you; this Quran has been revealed to me that I may therewith warn you and whomsoever it may reach. Can you verily bear witness that besides Allah there are other aliha (gods)?" Say "I bear no (such) witness!" Say: "But in truth He (Allah) is the only one Ilah (God). And truly I am innocent of what you join in worship with Him."
: Those to whom We have given the Scripture (Jews and Christians) recognize him (i.e. Muhammad SAW as a Messenger of Allah, and they also know that there is no Ilah (God) but Allah and Islam is Allah's Religion), as they recognize their own sons. Those who destroy themselves will not believe. (Tafsir At-Tabari)
: And who does more wrong than he who invents a lie against Allah or rejects His Ayat (proofs, evidences, verses, lessons, revelations, etc.)? Verily, the Zalimun (polytheists and wrong-doers, etc.) shall never be successful.
