And [recall] when you said, "O Moses, we can never endure one [kind of] food. So call upon your Lord to bring forth for us from the earth its green herbs and its cucumbers and its garlic and its lentils and its onions." [Moses] said, "Would you exchange what is better for what is less? Go into [any] settlement and indeed, you will have what you have asked." And they were covered with humiliation and poverty and returned with anger from Allāh [upon them]. That was because they [repeatedly] disbelieved in the signs of Allāh and killed the prophets without right. That was because they disobeyed and were [habitually] transgressing.
Also, remember when you were ungrateful for the blessings of your Lord, and became tired of the manna and quails He sent down to you, and said that you would not put up with one type of food. So, you asked Moses (peace be upon him) to ask Allah to produce herbs, vegetables, cucumbers, grains, lentils and onions from the plants on earth for you to consume. Moses said, disapproving of your request, that you wanted to exchange manna and quails which were better and nobler and came to you without effort or work, for what was lesser and worse. You were told to go down from this land to any town, and that you would find what you had asked for in its fields and markets. Due to following whims and repeatedly turning away from what Allah chose for them, they were disgraced, given poverty and misery. They earned Allah’s anger, because they turned away from His religion, and disbelieved His signs, and unjustly and brutally killed His prophets – all because they rebelled against Allah and used to transgress His limits.
