Ayyub and Ibn "Jubair both narrated it from "'Ikrimah bin Khalid from Sa'id bin Jubair on the authority of Ibn "Abbas. Ibn Juraij narrated it from "Abd Al Hamid bin Rafi' from "Ata from Ibn "Abbas. Al A'mash narrated it from Malik bin Al Harith on the authority of Ibn "Abbas. They all said about the divorce by three pronouncements. He allowed it and said" (Your wife) has been separated from you similar to the tradition narrated by Isma'il from Ayub from "Abd Allaah bin Kathir."
Abu Dawud said "Hammad bin Zaid narrated it from Ayyub from "Ikrimah on the authority of Ibn "Abbas. This version adds If he said "You are divorced three times saying in one pronouncement, it constitutes a single (divorce). Isma'il bin Ibrahim narrated it from Ayyub from "Ikrimah. This is his ("Ikrimah's) statement. He did not mention the name of Ibn "Abbas. He narrated it as a statement of "Ikrimah."
