Ibn ‘Umar (may Allaah be pleased with him) narrated that when the Prophet (peace and blessings of Allaah be upon him) started his prayer, he would say “Allaahu akbar” and raise his hands, when he bowed in rukoo’ he would raise his hands, when he said “Sami’a Allaahu liman hamidah [Allaah hears those who praise Him]” he would raise his hands, and when he stood up after two Rak’ahs he would raise his hands.
(Reported by al-Bukhaari, 2/222; Abu Dawood, 1/197).
The meaning of “when he stood up after two Rak’ahs he would raise his hands” is, when he stood up after the first Tashahhud.
The hands may be raised to the level of the shoulders or the ears.
