The water should be Tahir, and clean, not sullied with dirt, even if that dirt is Tahir. The water should be pure, and not mixed. The water should be Mubah (permissible for use).
The container of the water, used by the person concerned for Wudhu, should be Mubah (permissible for use by him). As an obligatory precaution, the container of the water used for Wudhu should not be made of gold or silver.
That parts of the body on which Wudhu is performed, should be Tahir, at the time of washing and wiping. The person doing Wudhu should have sufficient time at his disposal for Wudhu and namaz. Otherwiae he should do Taimum. One should perform Wudhu with the niyyat of Qurbat i.e. to obey the orders of Allah.
Wudhu should be performed in the prescribed sequence, that is, he should first wash his face, then his right hand and then his left hand, and thereafter, he should wipe his head and then the feet. He should wipe the right foot first and then the left. The acts of Wudhu should be done one after the other, without time gap in between.
There should be no impediment in the way of water reaching the parts of Wudhu. A person doing Wudhu should wash his hands and face and wipe his head and feet himself.
There should be no constraint for using water, i.e., using the water is not harmful to him. That parts of the body on which wiping is performed (the frontal part of the head and feet), should be Tahir, at the time wiping.
In Wudhu, it is obligatory to wash the face and hands, and to wipe the front portion of the head and the upper part of two feet. The length of the face should be washed from the upper part of the forehead, where hair grow, up to the farthest end of the chin, and its breadth should be washed to the part covered between the thumb and the middle finger. Then, one should first wash the right hand and then the left hand, from the elbows to the tips of the fingers. In order to ensure that each elbow has been washed thoroughly, one should include some portion above the elbow in washing.
Then wipe the front part of the head with the wetness which is in his hand; the recommended precaution is that he should wipe it with the palm of his right hand, from the upper part, downwards. ◦ The part on which wiping should be performed, is one fourth frontal part of the head. The recommended precaution is that the length should be equal to one finger, and its breadth should be equal to three joined fingers.
Then one should wipe with the moisture present in ones hands, ones feet from any toe of the foot up to the joint. As a recommended precaution, the right foot should be wiped with the right hand, and the left foot with the left hand. ◦ Wiping of the feet can have any breadth, but it is better that the breadth of the wiping should be equal to three joined fingers, and it is still better that the wiping of the entire foot is done with the entire hand.
Wudhu becomes void on account of the following seven things: Passing of urine. Excretion. Passing wind from the rear. A sleep, deep enough to restrict sight and hearing. Things on account of which a person loses his sensibility, like insanity, intoxication or unconsciousness. Istihaza. Janabat, and, as a recommended precaution, every state which requires Ghusl.

If the body becomes Najas after berforming Widwa, will your wudhwa be void? How can you perform Wudhwa when you have a bandage on the parts of Wudhwa? Is the ink that had dried on the parts of Wudhwa a barrier to perform wudhu? And what if you find it after performing prayes?
