Musnad Abu Ya'la al-Mawsili 6:102

Muhammad ibn Ishaq al-Musayyibi narrated to us, Abdullah ibn Nafi’ narrated to us, from Khalid ibn Iyas, from ‘Amir ibn Sa’d ibn Abi Waqqas, from his father, that the Prophet (peace and blessings of Allah be upon him) said: "Indeed, Allah is Good and loves goodness, Clean and loves cleanliness, Generous and loves generosity, Munificent and loves munificence. So clean your houses and do not resemble the Jews who collect refuse in their homes."
