Issue 137: the following conditions determine the correctness and validity of Wudhu and even if one of them is not observed, the Wudhu will be void:

1. The water must be pure.

2. The water must be permissible to use (Mubah; not usurped)

3. The water must be Mutlaq (not Mudhaf)

Issue 138: The Wudhu performed with impure water is void, even if one does not know or has forgotten that the water is impure, and if they have said prayer with that Wudhu, they must perform it with a correct Wudhu again.

4. The parts of the body involved in Wudhu must be pure.

5. Anything which may prevent the water from reaching the parts involved must be removed.

Q139: Because of their jobs, some people (like painters, auto mechanics and carpenters) are involved in handling paints, glues, grease and the like, and sometimes some traces of these things, do not wash off despite the careful wash before performing ablutions. What is the verdict on this?

A: If it does not prevent the water from reaching the skin, it does not matter.

Q140: I have burned my frontal hair and I wear artificial hair. What are the verdicts on wiping and the Ghusl of such artificial hair?

A: In this case, one must wipe the skin, and if any intervening thing like artificial hair prevents the water from reaching the skin, the wiping and the Ghusl will be void, but if the artificial hair is planted in the skin so that it is impossible or difficult to remove it, it is considered a case of Jabeerah (bandage or splints and the like used to protect or support the injured parts).

Q141: What is the verdict on the Wudhu or Ghusl of those who have tattoos on their body?

A: Tattoos and whatever under the skin do not invalidate the Wudhu or Ghusl.

6. One must perform Wudhu with the intention of Qurbah (obeying and worshiping Allah) and with no intention of hypocrisy.

7. Wudhu must be performed the way it was explained earlier.

8. To perform Wudhu, the acts must be done in the prescribed sequence one after the other with no time gap in between. Walking while performing Wudhu is not forbidden. So, if one takes some steps after washing their face and hands and then wipes their head and feet, their Wudhu will be correct.

9. A person performing Wudhu must wash their face and hands and wipe their head and feet themselves without any help of others. If anyone helps them in performing Wudhu, i.e., in pouring water on their hands and face and wiping their head and feet so that they both wash and wipe together, the Wudhu will be void; but holding the water container or hose pipe for a person performing Wudhu and even pouring water on their hands do not invalidate the Wudhu provided that the person him or herself does the washing and wiping acts. The sort of help which invalidates the Wudhu is that which is a help with the Wudhu itself so that observers would say that someone else performed the Wudhu for them.

10. One must have enough time to perform Wudhu and say prayers.
