Ali bin Abi Hamlah and Imam al-Awza'i say: Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) used to perform one thousand prostrations every day (perhaps this means that he used to perform one thousand rak'ahs).
This narration was recorded by Imam al-Tabarani in al-Mu'jam al-Kabir, and its chain is munqati' (broken).
