I see nothing wrong with praying for your team's win regardless of the team you might be supporting. Like Gina said, we can ask for whatever we wish.
I suppose this time around, we've seen more religious fervor from Pakistanis in their wishing for a win because of the rather dismal domestic situation in the country and people needed a reason to be happy even if just for a few moments - just to escape the bleak news they're hearing day in and day out. Even religious scholars joined in with prayers on television from what I've heard.
I know what you are saying.
But, wasting time and efforts especially on such useless effort to hit a round red ball across a big circle to be able to make a fast silly run between two ends of wooden pole ends is worse than praying to be better human being to be able to help other human and learn the ways to make lives better for needy, illeterate and sick people.
Come on.
Do you really think Allah/God cares what you do to pray for a stupid GAME which means hitting a red ball with a wooden flat bat?
Funny idea to say the least.
**Prayer rug is not meant for such a silly reason **my dear friends.
Go and wish for it but **do not try to disgrace a prayer rug, Hajj or Umrah **for such a low grade reason.
Please pray for a sick.
Pray for a needy.
Pray for peace.
Pray for your parents and family
Pray for better life and being able to help other human being.
I absolutely know what you might be thinking, but try to swallow what I said. **
A game is still a game at the end of day not worth emotional rampage.**
