If the chicken has been cooked properly, cooled down and kept in the fridge (in other words not left out at room temp for more than 2 hours) then the chicken is safe.
As the rice has just been cooked that is safe too. The danger with rice comes when you leave it out at room temperature after cooking it. The absolute limit is two hours and reheating it won't make it safe once exposed to room temperature for longer than that.
If you've done all of that it will be fine.
