Musnad Ahmad 1153:174

Abu Mu'awiyah narrated to us, Al-A'mash narrated to us, from Habib, from 'Ata', from 'Aisha, who said: A thief stole from her, so she invoked [evil] against him. The Messenger of Allah, peace and blessings of Allah be upon him, said to her: "Do not lighten [the sin] for him."
