Is it permissible to combine fasting the six days of Shawwal with making up fasts from Ramadan?

Question : The questioner, a woman, says: I had my menstruation in Ramadan, and the duration of the menstruation was six days. Then I wanted to make them up in Shawwal. So, if it happens that I fast the six days and make up the missed days in one day, is that permissible or not?

Answer : This is a matter in which even some students err. That is, if a person has fasts to make up from Ramadan and wants to delay making them up, but he fears that Shawwal will end, he fasts six days of Shawwal before making up the missed fasts, seeking the reward that the Messenger (peace and blessings be upon him) assigned to the one who fasts Ramadan and follows it with six days of Shawwal.
Some people think that if he fasts six days of Shawwal while he has fasts to make up from Ramadan, that will benefit him and he will obtain the reward of fasting the whole year. But this is an illusion and an error in his understanding, because the Prophet (peace and blessings be upon him) said . As for the one who has fasts to make up from Ramadan, is it said that he fasted Ramadan or that he fasted part of Ramadan? Part of Ramadan. So the six days cannot yield the reward of fasting the whole year unless he fasts the full month of Ramadan before them, because the Prophet (peace and blessings be upon him) made them dependent on Ramadan. They are with Ramadan like the regular voluntary prayer after the midday prayer, which follows the midday prayer. If a person prays the regular voluntary prayer after the midday prayer before he prays the midday prayer, does it benefit him or not?
It is strange; it does not benefit him, because it is before its time. Likewise, if he fasts six days of Shawwal before completing the making up of what he owes from Ramadan, he will not obtain the reward of fasting six days of Shawwal. Some of the brothers hold that this depends on the disagreement regarding the permissibility of voluntary fasting for one who has obligatory fasts to make up. The scholars, may Allah have mercy on them, differed on whether it is permissible for one who has fasts to make up from Ramadan to fast voluntarily or not.
Some of them said it is not permissible; rather, he must begin with the obligatory making up before the voluntary. And some said it is permissible, because the time for making up is spacious, since it is permissible for a person to delay making up until the time between him and the second Ramadan is equal to the number of days he owes. So the time for making up is spacious. And if its time is spacious, voluntary acts are permissible before it, by the evidence that the time for the obligatory prayer is spacious. So if a person performs a voluntary prayer before he performs the obligatory prayer, that voluntary prayer is valid. And this position is undoubtedly a position. Based on that, if a person fasts the Day of 'Arafah while he has fasts to make up from Ramadan, is the fasting of this day valid or not? According to this position, it is valid, because the time for making up is spacious. And according to the position of those who say that voluntary fasting is not valid until the obligatory is performed, if he fasts the Day of 'Arafah while he has fasts to make up from Ramadan, his fasting is not valid. These people cited as evidence the saying of Abu Bakr that Allah does not accept a voluntary act until the obligatory is completed. But the stronger position in my view is that the absolute or restricted voluntary act is valid before the making up, as long as its time is spacious, just like the prayer. As for fasting the six days of Shawwal, it does not depend on this disagreement, because the Messenger (peace and blessings be upon him) made them what? Dependent on Ramadan. So they are in the position of the regular voluntary prayer after the obligatory prayer. Do you see if a person wants to pray the regular voluntary prayer after the sunset prayer before the sunset prayer? Is it valid?
No, because it is dependent. Let us be mindful of this point, and I warned you before this session against rushing in rulings, and that it is obligatory for a person not to have superficial knowledge, but rather to be deliberate, pause, and look into the legal principles, which are to the Shari'ah what pegs are, and what mountains are to the earth, so that he does not err and thus go astray and be humbled. Many followers of knowledge think that this matter of fasting six days of Shawwal is like the matter of voluntary fasting for one who is not dependent on 'Umrah, meaning that the disagreement applies to it. But the matter, as I explained to you, is different.
