Water dripping from the limbs for wudhu to be valid

Q: A scholar mentioned that it is fardh (obligatory) for two drops of water to fall from every hair and part of the skin that must be washed in wuḍūʾ. If this does not occur, it will be considered as masah (wiping) rather than proper washing. However, another scholar stated that as long as two drops of water fall from the entire limb, the wuḍūʾ will be valid, and it will be considered as washed. Which of these opinions is correct according to the Sharīʿah? 

Providing the internet to someone who uses it for lawful and unlawful purposes

Q: What is the ruling on providing the internet to someone who uses it for lawful and unlawful purposes, given that some liken it to renting a house for a disobedient Muslim or an infidel?

If there is any doubt about it, is it more important to obey one's parents?
