Musannaf Ibn Abi Shayba 3:4761

'Abd al-Wahhab al-Thaqafi narrated to us, from Yahya ibn Sa'id, who said: Abu al-Zubayr informed me that Jabir fell ill while with them in Mecca. When he began to recover, he set out, and they went out with him, following him. When they reached a part of the road, the time for one of the prayers arrived, so he prayed with them while sitting, and they prayed with him while sitting.
