The Method and Amount of Feeding for Permanent Inability

The Shaykh : The method of feeding is of two types. The first type is to invite poor people, equal in number to the days missed, at the end of the month for lunch if it is after Ramadan, or for dinner, so he dines them or lunches with them. This is the first type. The second type is to give them grain and meat that sustains them. What is the amount of grain that must be provided or given to each poor person? Its amount is a quarter of a sa' (a dry measure of about 3 kg), because the sa' in the time of the Prophet (peace and blessings be upon him) was four mudds (a quarter of a sa'). I have measured the sa' and it came to two kilograms and forty grams. Since the sa' is for four, the amount of feeding for each poor person is half a kilogram and ten grams. If a person gives more out of caution, there is no blame on him, but this is the amount of the obligatory.
