21:106
إِنَّ فِى هَـٰذَا لَبَلَـٰغًا لِّقَوْمٍ عَـٰبِدِينَ
inna fī hādhā labalāghan liqawmin ʿābidīna
There truly is a message in this for the servants of God!
Verily, in this (the Qur’ân) there is a plain Message for people who worship Allâh (i.e. the true, real believers of Islâmic Monotheism who act practically on the Qur’ân and the Sunnah - legal ways of the Prophet صلى الله عليه وسلم).
