11. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Muhammad ibn Isma’il ibn Bazi’ from Hanan ibn Sadir from his father from abu Ja’far عليه السلام who has said the following: “Abu Dhar (may Allah be pleased with him) has said, ‘I heard the Messenger of Allah saying, “On the Day of Judgment the bridge will stand on two pillars: the kindred relations and safe keeping of trust. Those who maintain good relations with relatives and return the trust will pass the bridge safely to paradise but when the abuser of trust and neglector of good relations with relatives will try to pass the bridge no other deeds will benefit him and he will be thrown off the bridge into the fire.’”
