Majma al-Zawaid — Hadith 17345

Muhammad bin Abi Yahya narrates: I saw Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both); he saw a man supplicating with both hands raised, doing so before he had finished his prayer. When he had finished the prayer, Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both) said: The Prophet (peace and blessings be upon him) would not raise his hands until he had finished his prayer.
Al-Tabarani recorded it, and in giving his biography he said: Muhammad bin Abi Yahya al-Aslami narrated from Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both); the narrators of this report are 'thiqat' (trustworthy).
