Be generous towards those who are less fortunate than you ;Fulfill your obligations even if you don't have enough resources at your disposal ; Show mercy towards those in need ; Provide alternatives so they can still fulfill their obligations without having any financial burden on them .

This hadith explains the verse from the Quran which states that a person must pay a ransom if they are unable to fulfill their obligations. The ransom can be fulfilled by fasting for three days, giving charity to six poor persons, or offering sacrifice of one sheep. This hadith is an example of how this verse was applied in practice when Ka'b bin Ujrah was suffering from lice crawling on his face and he did not have any sheep to offer as sacrifice. Therefore, he was given an alternative option by Prophet Muhammad ﷺ - fasting for three days or giving charity to six poor people with half Sa' each. This hadith teaches us about being generous towards those who are less fortunate than us and also encourages us to fulfill our obligations even if we don't have enough resources at our disposal. It also shows us how Prophet Muhammad ﷺ showed mercy towards those in need and gave them alternatives so they could still fulfill their obligations without having any financial burden on them.
