91. There is no sin on women, children, the sick, the disabled who are chronically ill or blind, and the poor who do have any wealth to spend in order to equip themselves for remaining behind from going out, since they have valid excuses, as long as they are sincere to Allah and His Messenger and they practise His sacred law. Punishment will not fall on those who do good from among these people who are excused. Allah forgives the sins of those who do good and shows them mercy.
