The Six Fasts of Shawwaal

Q: Saum-19: Must the six fasts of shawwaal be observed consecutively or can there be breaks in between?

Answer: There are great virtues in observing the six fasts of shawwaal Rasulullaah SAW. said that the person who follows up the fast of Ramadhaan with the six of Shawwaal will be rewarded as if he fasted the entire gear However, it is not necessary to start the fasts immediately after the day of Eid, nor is it necessary to observe them all consecutively without a break. They may be observed apart from each other. And Allaah knows best what is most correct.
