Hadith.1546 - Yunus ibn Ammar reported: I complained to Imam Jafar ibn Muhammad Al-Sadiq (as) about a man who was harming me. Imam (as) said: "Pray against him." I replied: "I have already prayed against him." Imam (as) said: "Not like that. Instead, refrain from sins, fast, pray, and give charity. Then, in the last part of the night, perform ablution thoroughly, stand up and pray two units (rak'ahs). While in prostration, say: 'O’ Allah (swt), so-and-so (mention his name) has harmed me. O’ Allah (swt), weaken his body, cut off his influence, shorten his lifespan, and hasten this upon him this year.'" He said: I did so, and it wasn't long before he perished.
