Musnad Ahmad 30:1399

'Affan narrated to us, Aban al-'Attar narrated to us, he said: Yahya ibn Abi Kathir narrated to me, he said: Abu Salamah ibn 'Abd al-Rahman narrated to me, from Abu Hurairah, that the Prophet of Allah, may Allah bless him and grant him peace, said: "The believer is jealous, and Allah is jealous. And from the jealousy of Allah is that the believer commits what Allah has forbidden."
