Is my prayer for Dhuhr, Asr, Maghrib, and Isha valid after making up the Fajr prayer due to a water cut-off throughout the day, or what should I do?

Washing after menstruation (ghusl) becomes obligatory when the bleeding stops and the time for prayer begins, based on the Almighty's saying: "So keep away from women during menstruation. And do not approach them until they are pure. And when they have purified themselves, then come to them from where Allah has ordered you." If water is not available, then tayammum (dry ablution) becomes obligatory, based on the Almighty’s saying: "and you find no water, then perform tayammum with clean earth and wipe over your faces and your hands with it." There is no need for her to repeat the prayer if she prayed with tayammum and the time for that prayer expired. However, if she did not strive to find water, then found it, and the time for prayer had not yet expired, the Malikis recommend repeating the prayer after performing ghusl. If you omitted prayers due to ignorance of the ruling, then made them up after performing ghusl, the obligation is lifted from you, and you should seek Allah's forgiveness. It is advisable to always seek religious verdicts (fatwa) when facing any religious ambiguity.
