Narrated to us Ishaq ibn Ibrahim: informed us Muhammad ibn Bakr. (Another chain:) And narrated to us Hasan al-Hulwani: narrated to us Abd al-Razzaq — and the two were close in wording — both said: informed us Ibn Jurayj: informed me Abu al-Zubayr that he heard Tawus saying: We said to Ibn Abbas regarding sitting on the heels (al-iq'a') upon the feet, and he said: "It is the Sunnah." So we said to him: "Indeed, we see it as harshness toward the man." Ibn Abbas said: "Rather, it is the Sunnah of your Prophet, peace be upon him."
