Sayyiduna Anas (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "When you judge, be just; and when you kill (in retribution or for some lawful reason), do it in a good manner, for Allah, the Mighty and Majestic, is Excellent (Muhsin) and loves excellence."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated these two hadiths from Qatadah except Imran al-Qattan, and Muhammad bin Bilal is alone in narrating them."
