Withholding due to the sanctity of time is the continuation of fasting after its invalidity, and the reason for this is observing the sanctity of time during the day in Ramadan in particular, and it is in the right of the one who invalidates his fast during the day in Ramadan, and it is like the corruption of the Hajj, where the one who spoiled his Hajj is obliged to proceed with his invalidity, which is unlike prayer, for example. His prayer does not continue in it, rather he exits from it if possible, and whoever invalidates his fast by what invalidates the fast; Fasting is not considered in Sharia law. Because the invalidity of fasting, i.e., its corruption, means leaving worship and not taking into consideration fasting, which is either during the day in Ramadan or at other times, if it is not during the day in Ramadan; He does not have to continue with an invalid fast, whether his fast is voluntary or obligatory, such as making up the fast.
