Rules Regarding conditions of Wudhu

1. The Wudhu that is performed with Najis and mixed water is void – whether one knows that the water is Najis or mixed, or one does not know, of it the person had forgotten.
2. The water for Wudhu must be Mubah; therefore in the following instances, the Wudhu is void:
   • Performing Wudhu with water whose owner is not happy with his water being used (His displeasure is known).
   • That water which is not known if its owner is happy or not by its use.
   • Water that has been donated (Waqf) to specific people, which is used by other than those specified. For example, the pools of most Madaras (schools) which have been given as a donation to those of that specific Madrasah (school), and the rooms of Wudhu in most Masjids that have been specifically donated for those people who read their Salat in that Masjid.
3.  Performing Wudhu from a large river or lake is permissible even if the person does not know whether its owner is content or not. However, if the owner prevents one from performing Wudhu there, then according to Ihtiyat Wajib, one must not perform Wudhu there.
4. If the water is in a usurped utensil, and one has no access to any other water, then one must perform Tayammum. If someone performs Wudhu with such water, his Wudhu is void.
5. The parts to be washed or wiped in Wudhu - for example the face, arms, and feet must be Tahir.
6. If there is something on the face or arms that prevents water from reaching there, it must be removed in order to perform the Wudhu.
7. If there is something on the areas that the wiping is to be done on (on top of the head or the feet) that does not prevent water from reaching there, it must still be removed, since there must not be anything between the hand and the area of wiping.
8. In the event that the effects of the ink of a pen, the spot of paint, and oil/grease, and cream are not remaining (on the skin) and it is not an obstacle or barrier for performing Wudhu, then it is not a problem. However, if it is a covering that prevents water from reaching the skin, then it must be removed.
9. If something is stuck on the skin or on one of the areas of Wudhu, but it is not known whether it will prevent water from reaching that area or not, then it must be removed or the water must be made to flow underneath it.
10. The actions of Wudhu must be done in the following sequence (Tartib):

    The face must first be washed, followed by the washing of the right arm, then the left arm, and thereafter, the head and feet must be wiped. According to Ihtiyat, the right foot must be wiped before the left foot, and if the Wudhu is not performed in this sequence, then the Wudhu will be void.

11. Muwalat - this means that each action must be performed one after the other, with no lapse of time between the actions.
12. If between the actions of Wudhu, a period of time passes such that when one decides to wash or wipe a particular place, one notices that the moisture of all the places that have previously been washed or wiped have become dry, the Wudhu will become void.
13. Someone who is able to perform the actions of Wudhu must not seek assistance from others. Therefore, if someone else washes the face and arms of the person who needs to perform Wudhu or performs the wiping for him, then his Wudhu will be void.
14. Someone who is not able to perform Wudhu on his own must perform Wudhu with the help of another person, but he himself must make the intention.
15. Someone who knows he will get sick or fears that he will become ill, must perform Tayammum; and if he still performs Wudhu, it will be void. However, if one does not know that the water would be harmful, and performed Wudhu, and later, finds out that the water was harmful, then his Wudhu is correct.
16. Wudhu must be performed with the intention of “seeking nearness to Allah,” meaning for the wish or desire of Allah (SWT) one is performing Wudhu. It is not necessary that the Niyyat be “spoken” or even “mentioned” in the heart, rather even if one knows that he is performing Wudhu to obey the commandment of Allah, this too is sufficient. Therefore, if one was asked, “What are you doing?” - his response would be: “I am performing Wudhu.”
17. If the time of Salat is so short that if a person performs Wudhu, the complete Salat or a part of it will be performed after its time, then he must perform Tayammum. However, if the performing of Wudhu and Tayammum takes the same amount of time, then he must perform Wudhu.
