Islamic "charity" not even to fellow Muslims?

Pakistan Monsoons--World Muslims Not Helping Muslims
Muslims are not commanded to assist non-Muslims. To do so is a waste of money, because they are going to Hell anyway. The Qur'an and Hadith command that money flow either between Muslims or from non-Muslims to Muslims (Qur'an 9:29).
http://www.thereligionofpeace.com/Quran ... relief.htm states that neither has the Islamic community ever been particularly keen on disaster relief, even for Muslim victims. This is because the Qur'an teaches that disasters that befall communities are punishment from Allah.
What compelling reason is there to assist Islamic countries in desperate need when they refuse to help their very own? Billions for war, violence, and insurrection; but none for compassion; none for food, shelter, clothing, and medical attention?
1.3 Billion Muslims in the world could resolve the Pakistan tragedy in a New York Minute, but it is practically against their religion to give aid for those suffering from disasters, attributing them to the deity as retribution for wrong-doing.
Muhammad routinely used natural disaster as a threat to compel others to believe in his claim to be a prophet. The Qur'an specifically says that earthquake and famine are sent by Allah as punishment for the sin of the people (usually unbelief). There is no theological basis for helping those whom Allah is trying to hurt.
