The Quran

فَرَجَعَ موسىٰ إِلىٰ قَومِهِ غَضبانَ أَسِفًا ۚ قالَ يا قَومِ أَلَم يَعِدكُم رَبُّكُم وَعدًا حَسَنًا ۚ أَفَطالَ عَلَيكُمُ العَهدُ أَم أَرَدتُم أَن يَحِلَّ عَلَيكُم غَضَبٌ مِن رَبِّكُم فَأَخلَفتُم مَوعِدي

Muhammad Asad

Thereupon Moses returned to his people full of wrath and sorrow, [and] exclaimed: "O my people! Did not your Sustainer hold out [many] a goodly promise to you? Did, then, [the fulfilment of] this promise seem to you too long in coming?¹ Or are you, perchance, determined to see your Sustainer's condemnation fall upon you,² and so you broke your promise to me?"

Or, according to Zamakhshari: "Did, then, the time [of my absence] seem too long to you?" (It is to be noted that the term 'ahd signifies a "time" or "period" as well as a "covenant" or "promise".)
Lit., "Or have you decided that condemnation by your Sustainer should fall due upon you?"- ie., "are you determined to disregard the consequences of your doings?"
