Narrated Abdullah ibn Abbas: The Messenger of Allah (ﷺ) stayed fifteen days in Mecca in the year of Conquest. Shortening the prayer. Abu Dawud said: This tradition has also been transmitted by 'Abdah b. Sulaiman, Ahmad b. Khalid al-Wahbi, and Salamah b. Fadli on the authority of Ibn Ishaq ; but they did not mention the name of Ibn 'Abbas
