1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Ahmad ibn Muhammad ibn abu Nasr from Muhammad ibn ‘Ubayd Allah who has said the following: “I heard al-Rida عليه السلام saying, ‘A man cannot become a worshipper until he becomes a forbearing one. A man in the tribe of Israel wanting to become a worshipper had to keep silent for ten years before he could be considered a worshipper.’”
