Surah Al-'Ankabut 29:51

أَوَلَمْ يَكْفِهِمْ أَنَّآ أَنزَلْنَا عَلَيْكَ ٱلْكِتَـٰبَ يُتْلَىٰ عَلَيْهِمْ ۚ إِنَّ فِى ذَٰلِكَ لَرَحْمَةً وَذِكْرَىٰ لِقَوْمٍ يُؤْمِنُونَ

And is it not sufficient for them that We revealed to you the Book [i.e., the Qur’ān] which is recited to them? Indeed in that is a mercy and reminder for a people who believe.

Translation: Saheeh International

Tafsir

Is it not sufficient for them regarding what they have demanded that We have revealed to you the Book the Qur’ān which is recited to them? — as it constitutes a ongoing sign that will never terminate in contrast to the signs mentioned. Surely in that Book is mercy and a reminder an admonition for a people who believe.
