Surah Yunus — Ayah 101 (10:101)
قُلِ ٱنظُرُواْ مَاذَا فِي ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِۚ وَمَا تُغۡنِي ٱلۡأٓيَٰتُ وَٱلنُّذُرُ عَن قَوۡمٖ لَّا يُؤۡمِنُونَ ١٠١
English translation (Saheeh International)
Say, "Observe what is in the heavens and the earth." But of no avail will be signs or warners to a people who do not believe.
Brief commentary
Say, O Messenger, to the idolaters who ask you for signs: Think about the signs that are in the heavens and the earth, which indicate Allah’s Oneness and power. Sending down signs and messengers are of no use for people who will not believe because of their insistence on disbelief.
