The word(s) "sorrow" appears 7 time(s) in 7 verse(s) in Quran in Muhammad Pickthal translation.

(1) When ye climbed (the hill) and paid no heed to anyone, while the messenger, in your rear, was calling you (to fight). Therefor He rewarded you grief for (his) grief, that (He might teach) you not to sorrow either for that which ye missed or for that which befell you. Allah is Informed of what ye do.

(2) So he turned from them and said: O my people! I delivered my Lord's messages unto you and gave you good advice; then how can I sorrow for a people that rejected (truth)?

(3) Nor unto those whom, when they came to thee (asking) that thou shouldst mount them, thou didst tell: I cannot find whereon to mount you. They turned back with eyes flowing with tears, for sorrow that they could not find the means to spend.

(4) And when they went in before Joseph, he took his brother unto him, saying: Lo! I, even I, am thy brother, therefore sorrow not for what they did.

(5) And he turned away from them and said: Alas, my grief for Joseph! And his eyes were whitened with the sorrow that he was suppressing.

(6) When thy sister went and said: Shall I show you one who will nurse him? and we restored thee to thy mother that her eyes might be refreshed and might not sorrow. And thou didst kill a man and We delivered thee from great distress, and tried thee with a heavy trial. And thou didst tarry years among the folk of Midian. Then camest thou (hither) by (My) providence, O Moses,

(7) And the family of Pharaoh took him up, that he might become for them an enemy and a sorrow, Lo! Pharaoh and Haman and their hosts were ever sinning.
