The remedy for shortfalls in obligatory Salahs

Q 2: What is the ruling on whoever performs Nawafil (Supererogatory prayer) while sitting, as in case of Sunnah offered after the Obligatory prayer without a legal excuse for sitting?

A: It is permissible to offer Nafilah while sitting, but the reward in this case will be half of that granted if the person offering prayer stands while being able. Whereas if a person performs prayer in the sitting position due to illness and suchlike, they will be granted the full reward, for the saying of the Prophet (peace be upon him): When a servant of Allah suffers from illness or sets on a journey, he will be granted the equal reward of whatever good work he is used to do when he is healthy or resident (in his home). Narrated by Al-Bukhari in his Sahih (Authentic Book of Hadith). May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
