I asked Qasim bin Ismail Qarshi, who was a Mamtur : What did you hear from Muhammad bin Abu Hamza? He replied: Only one tradition. But after that a large number traditions were issued by him and he narrated them all from Muhammad bin Abi Hamza. Ibn Rabah also says: I asked Qasim: How many traditions have you heard from Hannan? He replied: Four or five. But later on a large number of traditions were issued by Qasim, which he narrated from Hannan.
