Don't Curse; Pray For Them

He said: "Verily, I was not sent to invoke curses, but rather I was only sent as mercy" (Sahih Muslim 2599).

And when the arrows of Thaqif had wounded the Companions and they asked him to pray against them, he could have cursed them but prayed for their guidance instead: "O Allah, guide the tribe of Thaqif!"

(Sunan al-Tirmidhi 3942). That is the Sunnah of mercy - not pretending evil doesn't exist, not excusing injustice, but remembering that guidance can turn an enemy into a brother.

Don't be too quick to ask Allah to destroy someone He may choose to guide. Allaahul Musta'aan.
