Jabir bin Zayd (may Allah have mercy on him) says that he heard Ibn Abbas (may Allah be pleased with them both) say: I prayed with the Prophet (peace and blessings be upon him) eight (rak'ahs) together and seven together. I said: O Abu al-Sha'tha', I think he delayed Zuhr and prayed Asr early, and delayed Maghrib and prayed Isha early. He said: I think so too.
