The noble wife of the Prophet Muhammad (peace be upon him), Sayyidah Hafsah (may Allah be pleased with her), narrates: I never saw the Prophet Muhammad (peace be upon him) performing voluntary prayers (nawafil) while sitting, until one year before his passing, I saw him performing voluntary prayers while sitting. He would recite the Surah slowly and with pauses, to the extent that it seemed even longer than the Surah itself.
