﴿ وَدَاعِيًا إِلَى ٱللَّهِ بِإِذْنِهِۦ وَسِرَاجًۭا مُّنِيرًۭا ﴾

“and as one who summons [all men] to God by His leave, and as a light-giving beacon.”

and as a summoner to God to obedience to Him by His leave by His command and as a illuminating lamp in other words the equivalent of it in terms of one’s being able to find guidance therewith.
