The Bee - 16:112 Allah gives as an example a successful community in security: The sustenance of that community used to reach them abundantly from every side. But then, when they became ungrateful for Allah´s blessings, Allah made them taste hunger and fear.
Who is this ungrateful people?
Sheva/34:15 The houses of the people of Sheba were a wonder, with two gardens to the right and left. Eat of the provision of your Lord and give thanks to Him. A beautiful land and a Forgiving Lord.
Sheva/34:16 But they turned away. So We sent the flood of the dam against them and turned their double gardens into double gardens with bitter fruits, tamarisk and some cedar trees
Sheva/34:17 This is how We punished them for their ingratitude. Do We punish anyone but the ungrateful?
Sheva/34:18 "We placed oases between them and the regions We made fertile, and We made it suitable for travel: "Travel therein in safety by night and by day."
Sheva/34:19 "They wronged themselves, saying: "Our Lord, our journeys have become distant."At last We destroyed them and buried them in history. In this are lessons for every patient and thankful person."
