At the al-Filisteen mosque in the Rimal area of Gaza City on Friday, the imam was preaching the necessity of brotherhood and unity. But on the steps after prayers, Hamas's economics minister explained what the conditions for Palestinian unity involved. Senior Hamas officials are demanding that the conditions for reconciliation should include an end to negotiations with Israel and to the peace process, a unity agreement under a banner of "resistance", and continued Hamas control of Gaza.
"Everyone recognises the need for reconciliation among Palestinians," said Abu Rushdi Zaza. "It will happen immediately if the Palestine Liberation Organisation [dominated by Fatah] can be rebuilt. But it must be understood that Hamas is the government. If international institutions want to do rebuilding projects in Gaza, then that is fine - but they must do it under our supervision.
Mahmoud Musleh, a Palestinian legislative council member aligned with Hamas, added: "The organisation that should be talking for the Palestinian people is the PLO. But it has not been speaking. If it does not rehabilitate itself, there will be dramatic changes. At present it does not represent the Palestinian people. They can longer make decisions. They do not own the power."
He continued: "There is a new balance of power emerging. For the first time, through the steadfastness of the resistance in Gaza, we have seen Israel's project halted."
And if one place is the symbol of the destruction wreaked in Gaza, it is the demolished houses of the Samouni family in Zeitoun, a place where the stink of death still seeps from out of the rubble.
A member of the family, who lost his father and his son, asks not to be identified for fear of being beaten by Hamas - as others were during the war - for criticising it. "No one from Hamas has come to offer us help. None of the leaders has been here. We were farmers, not fighters with a militant faction.
He pulls out a crumpled photograph showing a wedding scene. "This was my father. This, my son. After what happened to us here, I hate the name Hamas."
