This is kind of interesting. My guess is that the Palestinians are starting to wake up to the fact that the attempt to ban Muslim pilgrimage to Jerusalem is a classic case of "cutting off your nose to spite your face."

The chief Palestinian Muslim cleric [Shaikh Tayseer Al Timimi] is urging Muslims to visit Occupied Jerusalem, breaking a decades-long taboo against visiting the holy city because it would be considered support for Israel. "I withdraw my fatwa (edict) and now ask all Muslims and [Arab] Christians to creep into [Occupied] Jerusalem for a visit, satisfaction and shopping," Al Timimi said at a press conference in Cairo. "Come to the Palestinian hotels and come to the Palestinian markets," he said. Al Timimi had previously banned Muslims from visiting the city, arguing that would be considered normalizing relations with Israel.
If the Palestinians can't come up with a better source of income than foreign aid, then they're screwed. Of course, shooting rockets at people and constantly begging for retaliation is a great way to encourage foreign investment and tourism.
