إِنَّا عَرَضْنَا ٱلْأَمَانَةَ عَلَى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ وَٱلْجِبَالِ فَأَبَيْنَ أَن يَحْمِلْنَهَا وَأَشْفَقْنَ مِنْهَا وَحَمَلَهَا ٱلْإِنسَٰنُ ۖ إِنَّهُۥ كَانَ ظَلُومًۭا جَهُولًۭا
Lo! We offered the trust unto the heavens and the earth and the hills, but they shrank from bearing it and were afraid of it. And man assumed it. Lo! he hath proved a tyrant and a fool.
Surah Al-Ahzaab(33:72)
