6. My father and Muhammad ibn al-Hasan ibn Ahmad ibn al-Walid both said: Sa`d ibn `Abd Allah and `Abd Allah ibn Ja`far al-Himyari both said, on the authority of Ahmad ibn Muhammad ibn `Isa, on the authority of al-Hasan ibn `Ali ibn Fuddal, on the authority of Abu Jamilah al-Mufaddal ibn Salih, on the authority of Muhammad ibn `Ali al-Halabi that Abu `Abd Allah al-Sadiq said:

The servants (of Allah) have not been commanded to do anything more than what they are capable of doing. Therefore, people re able to refrain from whatever they have been enjoined to refrain, and whatever they do not have the ability to refrain from has not been required of them. However, there is no good in people (who do not fulfill their religious obligations.)
