Is the noble verse, "And during a portion of the night, wake up for prayer, a supererogatory act for you; it may be that your Lord will raise you to a praised station," exclusive to the Prophet (peace be upon him) alone? And are the two rak'ahs of night prayer considered a supererogatory act, or is night prayer something different from the mentioned supererogatory act?

Allah Almighty commanded His Prophet Muhammad, peace and blessings be upon him, to perform Tahajjud at night as a supererogatory act for him, after sleeping at night. It is also said that it was a special obligation for him due to his esteemed status with Allah, and an increase in his high standing and the elevation of his ranks. This explains the saying of Allah Almighty: "as an additional devotion for you," contrary to the rest of the Ummah for whom supererogatory acts atone for their sins. This Tahajjud is connected to the Praised Station (al-Maqam al-Mahmud) on the Day of Resurrection, which is the station of the Great Intercession where all, from the first to the last, will praise him. Night vigil (Qiyam (definition) al-Layl) is a confirmed Sunnah (definition) for all Muslims, and the Prophet, peace and blessings be upon him, consistently performed it and encouraged it. A supererogatory act includes all prayers other than the obligatory ones.
