Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "A body that has been nourished with the unlawful will not enter Paradise."
Abu Ya'la, al-Bazzar and al-Tabarani in al-Mu'jam al-Awsat recorded it. The narrators of Abu Ya'la are thiqat (trustworthy), though there is disagreement about some of them.
