A: All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions.Urine is Najis (ritually impure). If the drops
that fall on him are urine, it is obligatory to wash the spots where they fell on the body or clothes, and wiping them with water is not sufficient. The same applies if they were water drops poured over the urine.
During Wudu’, is it sufficient to pour water over each limb once and rub the rest of it? Is it permissible to wash each limb only once during Wudu’ and then to pray?
(Part No. 5; Page No. 237) A: It is sufficient for anyone performing Wudu’ to pour water over every part of the body required to be washed in Wudu’, provided that water covers the whole part. Furthermore, washing the part for the second and third times are Sunnah (supererogatory act of worship following the example of the Prophet). However, if someone washes each part once without making sure that it is fully covered with water, their Wudu’ is invalid, even if they rub the rest of the part with water.
