Types of water that can be consumed whilst standing

QUERY
Which types of water should we stand and drink, for example, left over water that a Muslim drank, water from a fountain, left over water of wudhu, and Zam Zam water. Should one stand and drink all these types of water or not?

THE ANSWER:
One may stand and drink Zam Zam and the remainder water of wudhu. The reason that people made a water fountain is because usually there is a lot of dirt under it and they don’t find the opportunity to sit. One should not stand and drink the water which another Muslim drank from.
