The word(s) "souls" appears 30 time(s) in 30 verse(s) in Quran in Muhammad Pickthal translation.

(1) Evil is that for which they sell their souls: that they should disbelieve in that which Allah hath revealed, grudging that Allah should reveal of His bounty unto whom He will of His slaves. They have incurred anger upon anger. For disbelievers is a shameful doom.

(2) And follow that which the devils falsely related against the kingdom of Solomon. Solomon disbelieved not; but the devils disbelieved, teaching mankind magic and that which was revealed to the two angels in Babel, Harut and Marut. Nor did they (the two angels) teach it to anyone till they had said: We are only a temptation, therefore disbelieve not (in the guidance of Allah). And from these two (angles) people learn that by which they cause division between man and wife; but they injure thereby no-one save by Allah's leave. And they learn that which harmeth them and profiteth them not. And surely they do know that he who trafficketh therein will have no (happy) portion in the Hereafter; and surely evil is the price for which they sell their souls, if they but knew.

(3) Establish worship, and pay the poor-due; and whatever of good ye send before (you) for your souls, ye will find it with Allah. Lo! Allah is Seer of what ye do.

(4) Your women are a tilth for you (to cultivate) so go to your tilth as ye will, and send (good deeds) before you for your souls, and fear Allah, and know that ye will (one day) meet Him. Give glad tidings to believers, (O Muhammad).

(5) And the likeness of those who spend their wealth in search of Allah's pleasure, and for the strengthening of their souls, is as the likeness of a garden on a height. The rainstorm smiteth it and it bringeth forth its fruit twofold. And if the rainstorm smite it not, then the shower. Allah is Seer of what ye do.

(6) And let not those who disbelieve imagine that the rein We give them bodeth good unto their souls. We only give them rein that they may grow in sinfulness. And theirs will be a shameful doom.

(7) Those are they, the secrets of whose hearts Allah knoweth. So oppose them and admonish them, and address them in plain terms about their souls.

(8) We made a covenant of old with the Children of Israel and We sent unto them messengers. As often as a messenger came unto them with that which their souls desired not (they became rebellious). Some (of them) they denied and some they slew.

(9) O ye who believe! Ye have charge of your own souls. He who erreth cannot injure you if ye are rightly guided. Unto Allah ye will all return; and then He will inform you of what ye used to do.

(10) Say: Unto whom belongeth whatsoever is in the heavens and the earth? Say: Unto Allah. He hath prescribed for Himself mercy, that He may bring you all together to the Day of Resurrection whereof there is no doubt. Those who ruin their souls will not believe.
