Al-Mukhtasar
إِنَّ ٱللَّهَ هُوَ رَبِّى وَرَبُّكُمْ فَٱعْبُدُوهُ ۚ هَـٰذَا صِرَٰطٌ مُّسْتَقِيمٌ ﴿٦٤﴾
“Indeed, Allah is my Lord and your Lord; we have no Lord other than Him, so devote your worship to Him alone. This monotheism that I call you towards and devotion of worship to Allah is the straight path in which there is no deviance.”
