8-Prostration (The sujud):

The prophet (sallallaahu 'alaihi wa sallam) would say takbeer:
Allaahu Akbar
This means: Allah is the greatest

& go down into sajdah saying :

Subhana Rabbi yal a'la
This means: How Perfect is my Lord, the Most High

Note :

1- You should say Subhana Rabbi yal a'la three times on each Sujud .
2- The right postion of Sujud:
a)You would support yourself on your palms [and spread them]
b)put his fingers together
c)point them towards the qiblah
d)Make your nose touch the ground cause the prophet said : There is no prayer for the one whose nose does not feel as much of the ground as the forehead
e)Put your knees and toes down firmly and point with the front of the toes towards the qiblah and put your heels together and keep your feet upright.
f)These are the seven limbs on which he (sallallaahu 'alaihi wa sallam) would prostrate: the palms, the knees, the feet, and the forehead and nose.
