The southern Spanish club trumped rivals Malaga 3-1 on Friday thanks to El-Arabi's goals with Yacine Brahimi the other star for Granada, setting up his team-mate's latter two strikes at the Estadio Nuevo Los Carmenes.
Granada took the lead three minutes into the second half in front of their home fans and although Juanmi equalised for Malaga in the 54th minute, El-Arabi and Brahimi combined after 58 and 76 minutes to secure three points for the hosts.
The hosts' opening goal came after a mistake by Malaga defender Marcos Angeleri, who lost possession to Fran Rico, and while the Granada midfielder's shot was saved, El-Arabi was there to knock home the rebound.
Brahimi's second assist was top quality with the Algerian winger sending a diagonal reverse pass to El-Arabi on the edge of the area and the 26-year-old finished first-time past Malaga's Wilfredo Caballero.
The goal secured Rodri's team their third straight win and took them out of the drop zone to 15th on 12 points, while Osasuna (10 points) slipped into relegation position vacated by Almeria.
