وَهُوَ ٱلۡقَاهِرُ فَوۡقَ عِبَادِهِۦۚ وَهُوَ ٱلۡحَكِيمُ ٱلۡخَبِيرُ
And He is the Irresistible, above His slaves, and He is the All-Wise, Well-Acquainted with all things.
قُلۡ أَيُّ شَيۡءٍ أَكۡبَرُ شَهَٰدَةٗۖ قُلِ ٱللَّهُۖ شَهِيدُۢ بَيۡنِي وَبَيۡنَكُمۡۚ وَأُوحِيَ إِلَيَّ هَٰذَا ٱلۡقُرۡءَانُ لِأُنذِرَكُم بِهِۦ وَمَنۢ بَلَغَۚ أَئِنَّكُمۡ لَتَشۡهَدُونَ أَنَّ مَعَ ٱللَّهِ ءَالِهَةً أُخۡرَىٰۚ قُل لَّآ أَشۡهَدُۚ قُلۡ إِنَّمَا هُوَ إِلَٰهٞ وَٰحِدٞ وَإِنَّنِي بَرِيٓءٞ مِّمَّا تُشۡرِكُونَ
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."
ٱلَّذِينَ ءَاتَيۡنَٰهُمُ ٱلۡكِتَٰبَ يَعۡرِفُونَهُۥ كَمَا يَعۡرِفُونَ أَبۡنَآءَهُمُۘ ٱلَّذِينَ خَسِرُوٓاْ أَنفُسَهُمۡ فَهُمۡ لَا يُؤۡمِنُونَ
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)
