"He also defended protesters using the chant "from the river to the sea, Palestine will be free" on marches.
Critics of the chant, including Israel and most Jewish groups, argue it implicitly calls for the destruction of Israel.
This interpretation is disputed by some pro-Palestinian activists who say that most people chanting it are calling for an end to Israel's occupation of the West Bank and blockade of Gaza, not the destruction of Israel itself.
Jewish Conservative MP Andrew Percy said the phrase, which was projected onto Parliament last week while a Gaza ceasefire debate was taking place in the Commons, was a "genocidal call".
Mr Jamal said his organisation had not projected the slogan on to Parliament but he defended the right of protesters to use it, "despite the rhetoric being used to demonise it".
He said it had "been used by the majority of Palestinians for decades" and "it speaks to the nature of how the rights of the Palestinian people are deprived".
He added: "It in no way calls for the abrogation of anybody else's rights.""
