Did the Arab League Summit in Riyadh give 48 hours to Israel to retreat from Jerusalem? No, that's not true. The Arab League Summit in Riyadh has not even taken place yet in order to give such notice.
The claim that the Arab League Summit in Riyadh had given Israel 48 hours to retreat from Jerusalem appeared in a video (archived here) where it was published by a TikTok account on April 6, 2023 under the title "giving 48 hours to Israel. May Allah grant victory to Muslims. Jerusalem is free."
This is what the post looked like on TikTok at the time of writing:

By the time of writing this article, the video was liked by 72,100 accounts, got 2,956 comments and was shared by 7,459 accounts. The vast majority of the comments seemed to be believing that the claim in the video was true.
However, the 32nd Arab League Summit has not even taken place yet. According to a statement by the League of Arab States, Saudi Arabia will host the Arab League Summit in Riyadh on May 19, 2023.
Moreover, there has been no official statement regarding giving any specific period of time to Israel to retreat from Jerusalem. Instead, one of the biggest topics of the 32nd Arab League Summit is considered to be the possibility of Syria's return to the summit.
"Assad's attendance at an Arab League summit would mark the most significant development in his rehabilitation within the Arab world since 2011 when Syria was suspended from the organization. Assad had been boycotted by many Western and Arab states over his brutal crackdown on protests - violence that led to a protracted civil war," a Reuters article noted on April 2, 2023.
