You know during niyaaz, there are some food and sometimes drinks which are used. Here is the dilemma: Suppose if someone does niyaz on a jucie or milk but the milk or juice is in a packet and after they have done the niyaz they drink it and throw away that packet in dustbin. Should one do that?

There is no matter if someone is doing so because your Niyyat for Nazr was that food and drink not it’s packet and box etc
