Mohammadi parted ways with Qatari side Al-Arabi last week and joined Al-Sailiya on loan until the end of the season.
The 28-year-old player joined Al-Arabi in 2020 from Portuguese team Aves and scored 12 goals in 27 matches for the team.
Mohammadi started his playing career in Tehran-based club Rah Ahan in 2014 and has also played in Sepahan.
Al-Sailiya sits 11th in the Qatar Stars League 12-team table.
