(Thwaha) 20 : 86
فَرَجَعَ مُوسَىٰ إِلَىٰ قَوْمِهِ غَضْبَانَ أَسِفًا ۚ قَالَ يَا قَوْمِ أَلَمْ يَعِدْكُمْ رَبُّكُمْ وَعْدًا حَسَنًا ۚ أَفَطَالَ عَلَيْكُمُ الْعَهْدُ أَمْ أَرَدْتُمْ أَنْ يَحِلَّ عَلَيْكُمْ غَضَبٌ مِنْ رَبِّكُمْ فَأَخْلَفْتُمْ مَوْعِدِي
Moses returned to his people in angry and grief. He asked: "Oh my people! Didn’t your Lord make you a Best Promise? Then, was the time too long for you, or did you wish that wrath from your Lord should fall upon you, so you broke your promise made with me?"
