Is it permissible for the worshiper to extend his hands after completing the Abrahamic prayer and the Tashahhud in the second Rak'ah, or must they remain in the Qabd position?

The Sunnah (definition) in the Tashahhud (definition) is to clench the pinky and the finger next to it, to form a circle with the thumb and middle finger, and to point with the index finger. Alternatively, one can clench the three fingers, place the thumb on the middle finger, and point with the index finger. The right hand remains in this position until the Salām or until standing for the third unit of prayer (rak'ah). There is no mention of extending the hand after the Tashahhud. As for the left hand, it should be placed extended on the left thigh or knee. This manner is recommended (mustahabb) and not obligatory (wajib (definition)), and the prayer is valid even if it is not observed.
