[٤/٦٩] رجال الكشي: عن حمدويه، عن محمد بن عيسي، عن يونس، عن حماد قال: كان أبو الحسن عليه السلام يأمر محمد بن حكيم أن يجالس أهل المدينة في مسجد رسول الله صلى الله عليه واله وأن يكلمهم ويخاصمهم حتى كلمهم في صاحب القبر وكان إذا انصرف إليه قال: ما قلت لهم وما قالوا لك ويرضى بذلك منه
4. [4/69] Rijal al-Kashshi: From Hamduwayh from Muhammad b. Isa from Yunus from Hammad who said: Abu al-Hasan عليه السلام used to order Muhammad b. Hukaym to sit with the people of Madina in the Masjid of the messenger of Allāh صلى الله عليه واله and to talk to them and debate with them – such that he even debated with them regarding the companion of the grave (i.e. Abu Bakr) – and when he (Muhammad b. Hukaym) used to go to meet him (the Imam) – he would ask: what did you say to them and what did they say to you? and he used to be pleased with that from him.
