Jubayr bin Mut'im · The Book of the Times (of Prayer)

It was narrated from Ibn 'Abbas that he prayed Al-Uula (Zuhr) and 'Asr together in Al-Basrah with nothing in between them, and he prayed Maghrib and 'Isha' together with nothing in between them. He did that because he was busy and Ibn 'Abbas said that he had prayed Zuhr and 'Isha' together with the Messenger of Allah (ﷺ) in Al-Madinah, eight Rak'ahs with nothing in between.
