Jabir ibn Abdullah:
A man stood on the day of Conquest (of Mecca) and said: Messenger of Allah, I have vowed to Allah that if He grants conquest of Mecca at your hands, I shall pray two rak'ahs in Jerusalem. He replied: Pray here. He repeated (his statement) to him and he said: Pray here. He again repeated (his statement) to him. He (the Prophet) replied: Pursue your own course, then.
Abu Dawud said: A similar tradition has been narrated by 'Abd al-Rahman b. 'Awf from the Prophet (ﷺ).
