Temper is mentioned in the Quran in these verses:
[20:25] He said, “My Lord, cool my temper.
[26:13] “I may lose my temper. My tongue gets tied; send for my brother Aaron.
[94:1] Did we not cool your temper?
[94:2] And we unloaded your load (of sins).
[94:3] One that burdened your back.
[94:4] We exalted you to an honorable position.
[94:5] With pain there is gain.
[94:6] Indeed, with pain there is gain.
[94:7] Whenever possible you shall strive.
[94:8] Seeking only your Lord.
