There is currently no evidence that Iran or Qatar knew about the timing of the attacks, and the US's position is that they don't believe it was known.

> Initial U.S. intelligence reports show that some Iranian leaders were surprised by the Islamist group's unprecedented attack from Gaza, U.S. sources said on Wednesday.

> A U.S. official said, however, that Iran, Israel's regional arch-foe, had likely been aware that Hamas was planning to take action against Israel "but without the precise timing or scope of what occurred" last weekend.

It's also a fairly low amount of money for already-rich Qatari royalty to risk running afoul of their access to US markets.
