When beginning the prayer:
• A man wearing sleeves brings his hands out as an Adab, then raises them to the prescribed level.
• Make the intention in the heart for the prayer being performed.
• Say the opening Takbir while standing when standing is required and one is able.
• The source cautions against stretching the initial Hamzah in the opening Takbir.
• Then place the right hand over the left without an unnecessary pause.
The opening Takbir itself is essential; details such as hand-raising and hand placement belong to the Sunnah/Adab form already studied.
