The Mother of the Believers, Sayyidah Safiyyah (may Allah be pleased with her), narrates: "The Messenger of Allah (peace and blessings be upon him) came in to me while four thousand date stones lay before me, on which I was glorifying Allah (tasbih). He (peace and blessings be upon him) said: 'O daughter of Huyayy! What is this?' I said: 'I am glorifying Allah with them.' He (peace and blessings be upon him) said: 'Since I have been standing by you, I have glorified Allah far more than this.' I said: 'O Messenger of Allah! Teach me (too).' He (peace and blessings be upon him) said: 'Say: Subhan Allahi 'adada ma khalaqa min shay' (Glory be to Allah, as many times as the number of everything He has created).'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated these hadiths from Kinanah, from Sayyidah Safiyyah (may Allah be pleased with her), except Hashim bin Sa'id al-Kufi, and Shadh (bin al-Fayyad) is alone in narrating them."
