Here is the step by step instructions on how to make wudu before the salah.
Step 1:
Intention. Since Islam teaches us that intention forms the basis of any action, it is necessary that, before you perform Wudu (Ablution), you make the niyyat or intention for it. This will not be a verbal act – you only have to mentally prepare yourself for an act that will cleanse and purify you.
Step 2:
Say Bismillah. Recite bismi-llāhi ar-raḥmāni ar-raḥīmi (In the name of Allah, the most Gracious, the most Merciful).
Step 3:
Begin by washing your hands. Completely wash your right hand three times with clean water, then move on to the left and repeat. When washing, remember not to miss any part of the hands – wash between the fingers and thumb, too.
