No, you shouldn’t repeat them as they are valid and correct.

Sheikh I made up some of my fasts after 15th of Shaban this year and last year . Now I came across a hadeeth which says it’s prohibited to fasts after 15th of Shaban . now should I repeat all those fasts ?

I usually dring water 2-3 mins before Fajr Azaan so that I can start fasting. But today, it was still 2 mins.in Azaan time, & I heard Azaan from a far away mosque, but not from my mosque.I drank water.And after that, I heard Azaan from my mosque. Is my fast valid? Cuz people say one must follow the Azaan timings of your own mosque, not far away mosques. Plz advs.

If someone does not complete their fasts from the previous ramadan before the next ramamdan comes do they have to also feed the poor for everyday that they delayed along with making up their fasts?
