As soon as Ramadan passes, Taraweeh ends, but fasting does not end yes, of course, it makes such a difference that the obligation of fasting ends there are some days in the year other than Ramadan when Prophet Muhammad (peace and blessings of Allah be upon him) encouraged fasting even though they are not compulsory but the rewards of these fasts are great. Fasting is the name of restraining oneself from hunger, thirst, and evil deeds for the sake of Allah Almighty.
Award of some optional ( Nawafil ) salat is more than other optional salat
In hadith, Hazrat Muhammad SAW said:
“That the best fast after Ramadan is on the 9th and 10th or 10th and 11th of Muharram”
The fasts that come immediately after Ramadan are the six fasts of Shawwal.
Abu Ayyub Al-Ansari relates that Allah’s Prophet Hazrat Muhammad (peace be upon him) says:
“Whoever fasts all the days of Ramadan and follows it with six days of Shawwal, it will be as he has fasted the whole year.” (Sahih Muslim, 1163)
However, some scholars say that it is not necessary to observe six consecutive fasts, dividing the fasts into a whole month, that is, two fasts in one week, two in the next week, for example, when you have holidays in a week like Saturday and Sunday keep fasts on those days and if there are no difficulties, then all fasts can keep it continuously. But that virtue of fasting can only be achieved even before the month of Shawwal has passed
But when it comes to which day fasting will be more rewarding then:
Hazrat Muhammad (peace and blessings of Allah be upon him) used to fast on Mondays and Thursdays throughout his life, which means that fasting on Mondays and Thursdays is Sunnah, so these days are more important in terms of fasting.
Missed fasts of Ramadan
If a person misses the fast due to a Shari reason, he should complete the count on any day of the year. In this regard, the Almighty has said in the Quran:
"If some of you are sick or on a journey, he should complete the count from other days. ”(Surat al-Baqarah 184).
Now, since the reward for fasting in Shawwal is greater than on other days, it would be better to keep fast those missed fasts of Ramadan in addition to the six fasts of Shawwal.
