1. Ali ibn Ibrahim has narrated from his father and Muhammad ibn Isma’il from Fadl ibn Shadhan all from Ibn Abi ‘Umayr from Ibrahim ibn ‘Abd al-Hamid from abu ‘Usamah Zayd al-Shahham from Abu ‘Abdillah  who has said the following: “Guard against al-Muhaqqarat (sins); they will not be forgiven.’ I then asked the Imam, ‘What is al-Muhaqqarat ?’ The Imam said, ‘A man commits a sin and says, “I will have Tuba (a tree in paradise) if I did not have any other sins.’”
