Musnad Abu Ya'la al-Mawsili 1:94

Abu Kurayb narrated to us, Mu'awiyah ibn Hisham narrated to us, from Shayban, from 'Amir, from Murrah, from Abu Bakr, from the Prophet (peace and blessings of Allah be upon him), who said: "The one who possesses a bad disposition shall not enter Paradise." "Cursed is he who harms a Muslim or deceives him."
