He saw the Prophet of Allah (ﷺ) raise his hands when he started to pray, and he narrated a similar report and added: "When he bowed he did likewise, and when he raised his head from bowing he did likewise, and when he raised his head from prostration he did likewise."
The Book of The At-Tatbiq (Clasping One's Hands Together)
Sunan an-Nasa'i - Hadith Reference: Sunan an-Nasa'i 1087
Textual Analysis
This narration establishes the sunnah of raising hands at four specific positions during prayer: at the opening takbir, when bowing (ruku'), when rising from bowing, and when rising from the first prostration.
Juridical Significance
The raising of hands demonstrates the transition between prayer postures and serves as physical manifestation of submission to Allah. This action accompanies the takbir, magnifying Allah with both word and deed.
Scholars differ regarding the precise manner of hand-raising, but agree on its recommended status based on this and similar authentic narrations from the Prophet's practice.
Spiritual Dimensions
Each hand-raising symbolizes casting aside worldly concerns and turning wholly to Allah. The repetition throughout prayer maintains continuous awareness of Divine Majesty and the worshipper's humble position before the Creator.
