Ruling on Missing Previous Ramadan’s Qadā’ Until the Next Ramadan Arrives
Source: Fatāwā Amunpuri by Shaykh Ghulam Mustafa Zaheer Amunpuri
❖ Question:
If a woman did not make up the missed fasts of the previous Ramadan and the next Ramadan has already begun, what should she do?
❖ Answer:
It is obligatory to make up (qadā’) the missed fasts of Ramadan before the next Ramadan begins. Exceeding this limit without a valid excuse is not permissible.
Therefore, if someone failed to make up the missed fasts until the next Ramadan arrived, she must:
① Repent (tawbah) for the delay, and
② After the current Ramadan, make up the missed fasts of both Ramadans.

Delaying the qadā’ of Ramadan fasts until the next Ramadan without excuse is sinful. Repentance is required, and the qadā’ of all missed fasts must still be observed afterward.
