Abu Bakr bin Quraysh informed us; al-Hasan bin Sufyan informed him; Ishaq bin Ibrahim al-Hanzali informed him; Ibrahim bin al-Hakam bin Aban informed him from his father, he from Ikrimah, he from Ibn Abbas, and he from the Prophet (peace and blessings be upon him), like the hadith of Musa bin Abd al-Aziz from al-Hakam. And it is also authentically established from Sayyiduna Abdullah bin Umar bin al-Khattab (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) taught his cousin Ja'far bin Abi Talib (may Allah be pleased with him) this prayer (Salat al-Tasbih) just as he had taught it to his uncle al-Abbas (may Allah be pleased with him).
