Making up for Salah missed unintentionally

Q: A person forgot to make up the missed Maghrib (Sunset) Prayer, and offered `Isha' (Night) Prayer, after which he remembered the missed Salah, is his Salah valid or not? What should he do in this case?

A: His `Isha' (Night) Prayer is valid according to the more correct of the two opinions maintained by scholars. There is no blame on him and he is excused by his forgetfulness, for Allah (Exalted be He) said: Our Lord! Punish us not if we forget or fall into error (Part No. 6; Page No. 24) and the Prophet (peace be upon him) said that Allah said: I did. Related by Muslim in his Sahih. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
