'Abd al-Wahid ibn Ghiyath narrated to us, Abu Janab narrated to us, he said: Ziyad al-Numayri narrated to me. Abu Janab said: He swore three oaths by Allah, besides whom there is no god, the Most Gracious, the Most Merciful, that he heard Anas ibn Malik, and he swore by Allah, besides whom there is no god, the Most Gracious, the Most Merciful, that he heard the Prophet, may Allah bless him and grant him peace, saying: "The intercession is for those who have committed major sins among my nation."
