Is it permissible to observe Sawm

Q 1: What is the ruling on someone who has days to make up for Ramadan and wants to fast voluntarily or (Part No. 10; Page No. 402) to fast the day of `Ashura (10th and 11th of Muhrram) with the intention of making up for the fasts he missed in Ramadan? Is it permissible for a person who owes days from Ramadan to fast on `Ashura? Is it permissible for a person who owes days from Ramadan to fast on `Ashura and one day after or before with the intention of making up missed days?

A: They should not observe voluntary fasts when they still owe one or more days from Ramadan. They should start with the fasts they missed in Ramadan, and then observe voluntary fasts. Second: If they fast the tenth and eleventh of Muharram with the intention of making up days they missed of Ramadan, it is permissible and will make up for two of the days that they missed. The Prophet (peace be upon him) said, Actions are judged but by intentions, and every person will have but that which he intended. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
