Humran (may Allah have mercy on him) relates: I heard Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) saying: I heard the Messenger of Allah (peace and blessings be upon him) saying: "Whoever says 'Subhan Allah, wal-hamdu lillah, wa la ilaha illallah, wallahu akbar' (Glory be to Allah, all praise is for Allah, there is none worthy of worship except Allah, and Allah is the Greatest), ten good deeds will be written for him for every letter. Whoever helps in a false lawsuit or dispute remains continually in the displeasure of Allah until he desists (from that act). Whoever's intercession becomes an obstacle to carrying out one of the prescribed punishments (hudud) of Allah has indeed opposed Allah in His command. And whoever slanders a believing man or a believing woman with what is not in them, Allah Almighty will confine him on the Day of Resurrection in radghat al-khabal (the mire of the pus and blood of the people of Hell) until he comes out of (the consequence of) what he said, and he will not be able to come out."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ata al-Khurasani, from Humran, except al-Qasim bin Abi Bazzah, and no one narrated it from al-Qasim bin Abi Bazzah except Fitr, and no one narrated it from Fitr except Ammar bin Ruzayq, while Abu al-Jawwab is alone in transmitting it from Ammar."
