Washing limbs more than three times during wudhu and water reaching the skin under the beard
Q: During wuzu, it is sunnat to wash the limbs of our body 3 times be it the face, hands or legs.
1. What if we feel that on 3 times we haven't fully wet the particular limb, can we then wash a particular limb more than 3 times? Will this invalidate the wudu or that just means we will leave the sunnat but wudu will be done?
2. As for cleaning the face during wuzu, is it necessary that water reaches in the gaps and the skin below the beard/moustache?
