Sunnats of Ruku (Males)

 1. When you have completed the recitation of Surah Faatihah and the qiraat, repeat the takbeer, and without raising your hands, go into ruku. 

Note: The takbeeraat-e-intiqaaliyyah (takbeer which is recited when moving from one posture to another) should be commenced as soon as one begins moving to the next posture and should only be completed when one reaches that posture.

2. Ensure that your back is kept in a straight line (completely level without bending it). Similarly, the shins (i.e. from the knee downwards) will be kept erect and the elbows will be kept straight.

3. Keep your head straight and in line with your back. You should neither raise your head nor lower it.

4. Grasp the knees firmly with the fingers spread apart.

5. Fix the gaze on the feet in the posture of ruku.
