Politics apni jaga, but I absolutely hate it when people start taking cheap shots regarding whether an indvidual practices or not, whether they practice correctly or not.
When we vote someone into power even Islamically we are supposed to vote for the person we believe will provide a just government for every single citizen. That is our duty.
Now Imran did live his life outside religion when he was young. He admits it in in his memoir. He says through college, and his crciket career he was spiritually diseased, and it wasn't until he was going through a rough patch and his mum told him to read the Quran to deal with it that he began his spiritual journey and became attatched to religion.
That's from the horses mouth and when it comes to religion we are supposed to believe what the person says. If you say you read namaz five times a day I am obligated to believe you do I am not allowed to be suspicious of you, and if I am suspicious I am obligated to keep those suspicions to myself.
Even if we go out together and it's time for namaz and you don't read it, I would be required to give you the benefit of the doubt because there could be any number of reasons why you missed the namaz. And as far as I know that one instance could have been an exception to the rule, not the rule itself.
In that picture he has his hands in the wrong position. However that is no basis on which to assume he doesn't read namaz. Maybe he slipped up and made a mistake that day.
As for the Shaukat Khanum stuff. Like Raindrops said, all the accounts are on their website. As far as I can see there is nothing untoward going on there.
Shaukat Khanum uses all the zakat money for treatment. Every single penny. Building maintenance, repairs, etc, are all made using the money raised at fundraisers.
