severe
in Edition Clear Qur'an by Talal Itani / Aal-i-Imraan (The Family of Imraan)

3:56As for those who disbelieve, I will punish them with a severe punishment, in this world and the next, and they will have no helpers.

3:120If something good happens to you, it upsets them; but if something bad befalls you, they rejoice at it. But if you persevere and maintain righteousness, their schemes will not harm you at all. God comprehends what they do.

3:125It is; but if you persevere and remain cautious, and they attack you suddenly, your Lord will reinforce you with five thousand angels, well trained.

3:186You will be tested through your possessions and your persons; and you will hear from those who received the Scripture before you, and from the idol worshipers, much abuse. But if you persevere and lead a righteous life—that indeed is a mark of great determination.
