Harun narrated to us, he said: Abu Abd al-Rahman said, and I heard it myself from Harun, Abdullah ibn Wahb narrated to us, he said: Haywah ibn Shurayh informed me, he said: Uqbah ibn Muslim informed me, from Abdullah ibn al-Harith ibn Juz' al-Zubaydi, he said: "We were one day with the Messenger of Allah, may Allah bless him and grant him peace, in the Suffah, and food was placed for us, so we ate. Then the prayer was established, and we prayed and did not perform ablution." Harun narrated to us, Abdullah ibn Wahb narrated to us, he said: Haywah narrated to me, from Uqbah ibn Muslim al-Tujibi, he said: I heard Abdullah ibn al-Harith ibn Juz' al-Zubaydi, one of the companions of the Prophet, may Allah bless him and grant him peace, saying: "Woe to the heels and the soles of the feet from the Fire on the Day of Resurrection." Abdullah said: "And he did not attribute it [to the Prophet]." Abdullah said: And I heard it myself from Harun.
