28-14 Muhammad ibn al-Hassan ibn Ahmad ibn al-Walid - may God be pleased with him - narrated that Muhammad ibn al-Hassan al-Saffar quoted Ahmad ibn Muhammad ibn Isa, on the authority of Muhammad ibn Sin’an, on the authority of Abdullah ibn Miskan, on the authority of Musa ibn Bakr,

“I asked Aba Abdullah as-Sadiq (MGB), ‘How much of one’s obligatory prayers must be compensated for if a person goes into a coma for one, two, three, four or more days?’ The Imam (MGB) replied, ‘I will give you a general instruction which covers this subject and whatever else of a similar nature. In any issue in which God prevents His servants from doing their duty, God accepts His servant’s excuse.’”Other narrators of this tradition have added that Aba Abdullah as-Sadiq (MGB) added, “’This is from those chapters which result in one-thousand chapters. This is one of the gates which opens up to one-thousand gates.”
