12. Muhammad ibn `Ali (my father) said: `Ali ibn al-Hasan al-Kufi on the authority of his father, on the authority of al-Husayn ibn Sayf, from his brother Ali, on the authority of his father Sayf ibn `Amirah, on the authority of `Amru ibn Shimr, on the authority of Abu Tufayl that `Ali said: A Muslim servant has only to say the words `There is no god but Allah,’ and they ascend (to Allah), breaking through physical barriers. As they do so, they obliterate his sins as they pass them by, stopping only when they reach his good deeds.
