Washing one's feet with used water in wudhu
Q: A person makes wudhu and then washes their feet by scooping water from a bucket and pouring the water over their feet in the same bucket of water. The bucket does not contain so much water. The person makes about 3 wudhus like this and then changes the water in the bucket. Is the washing of the feet valid in the second and third wudhu as the water could be used water?
