Salam Joseph,
In verse 4:43, Momineen are warned not to go for Salaat when their minds are beclouded. Does it mean only becloud or does this mean under the influence of intoxicants (such as wine)? Secondly if intoxicating is Haram why is Allah asking the Momineen not to perform prayers because Momin do not drink (as it is haram). Is this command earlier to declaring intoxicants Haram?
