The honourable Abul Barakt Amr bin Ibrahim bin Hamza Al-Alawy narrated from the honourable Abu Abdillah Mohammad bin ALI (ASWS) bin Abdul Rahman Al-Alawy, from Jaafar bin Mohammad Al-Hajib, from ALI bin Ahmad bin Amr, from Mohammad bin Mansour, from Harb bin Hasan Al-Sahhan, from Yahya bin Mosawer, from Abi Jarud, from MOHAMMAD BIN ALI (ASWS), who said:
O Abi Jarud! Are you (Shia) not pleased that your prayers are accepted, your Siyaam is accepted, and your Hajj is accepted? I swear to ALLAH (SWT) that others pray but it will not be accepted, they fast but it will not be accepted, and they go for Hajj but it will not be accepted.
