Sermon 70 of Nahj al-Balagha: Spoken on the morning of the day when Amir al-mu'minin was fatally struck with sword.

I was sitting when sleep overtook me. I saw the Prophet of Allah appear before me, and I said: "O Prophet of Allah! What crookedness and enmity I had to face from your nation. "The Prophet of Allah said: "Invoke (Allah) evil upon them," but I said, "Allah may change them for me with better ones and change me for them with an evil one”.
