Even if you think Sharon’s Temple Mount visit was provocative and Israeli police used excessive force on Sept 29, senior Palestinian figures later said the uprising was coming anyway and was planned, and Sharon was a convenient trigger.
1) Marwan Barghouti told The New Yorker: the explosion would have happened anyway; Sharon provided a good excuse. https://www.newyorker.com/magazine/2001/01/29/arafats-gift
2) PA communications minister Imad al Faluji: this intifada was planned in advance since Arafat returned from Camp David. https://foreignpolicy.com/2011/02/21/history-matters/
3) Suha Arafat said Arafat decided to start an intifada (MEMRI translation; CFR discusses it too). https://www.memri.org/tv/suha-arafat-widow-yasser-arafat-200... https://www.cfr.org/articles/arafat-and-second-intifada
Also, it is not just Israelis saying this. Mainstream sources record these admissions and describe the outbreak as Palestinian violence following the visit.
On Oslo: it was an interim framework with later permanent status talks, not a guaranteed rapid withdrawal and state. The PLO letter explicitly renounced terrorism and other violence. https://history.state.gov/milestones/1993-2000/oslo https://www.govinfo.gov/content/pkg/BILLS-107hr3743ih/html/B...
