2:57And We shaded you with clouds, and We sent down to you manna and quails: “Eat of the good things We have provided for you.” They did not wrong Us, but they used to wrong their own souls.

2:87We gave Moses the Scripture, and sent a succession of messengers after him. And We gave Jesus son of Mary the clear proofs, and We supported him with the Holy Spirit. Is it that whenever a messenger comes to you with anything your souls do not desire, you grew arrogant, calling some impostors, and killing others?

2:90Miserable is what they sold their souls for—rejecting what God has revealed, out of resentment that God would send down His grace upon whomever He chooses from among His servants. Thus they incurred wrath upon wrath. And there is a demeaning punishment for the disbelievers.

2:102And they followed what the devils taught during the reign of Salomon. It was not Solomon who disbelieved, but it was the devils who disbelieved. They taught the people witchcraft and what was revealed in Babylon to the two angels Harut and Marut. They did not teach anybody until they had said, “We are a test, so do not lose faith.” But they learned from them the means to cause separation between man and his wife. But they cannot harm anyone except with God's permission. And they learned what would harm them and not benefit them. Yet they knew that whoever deals in it will have no share in the Hereafter. Miserable is what they sold their souls for, if they only knew.

2:235You commit no error by announcing your engagement to women, or by keeping it to yourselves. God knows that you will be thinking about them. But do not meet them secretly, unless you have something proper to say. And do not confirm the marriage tie until the writing is fulfilled. And know that God knows what is in your souls, so beware of Him. And know that God is Forgiving and Forbearing.

2:265And the parable of those who spend their wealth seeking God’s approval, and to strengthen their souls, is that of a garden on a hillside. If heavy rain falls on it, its produce is doubled; and if no heavy rain falls, then dew is enough. God is seeing of everything you do.
