To raise the hands when standing

Q 1: How should the Takbir (saying: "Allahu Akbar [Allah is the Greatest]") after the first Tashahhud (testification recited in the sitting position in the second/last unit of Prayer) be recited? Should the person raise his hands when reciting the Takbir while sitting then stand up, or raise his hands just after he stands up? Which one is more preferable?

A: After the first Tashahud, a person should raise his hands and recite Takbir when he moves from the state of sitting to the state of standing.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
