In Musa’s agreement with the Caliphate club, a clause included allows him to leave when and if he can find a club in Europe.
Speaking on the move, the former Leicester forward, who is a free agent since leaving Saudi Arabian side Al Nassr in October, told BBC Sport Africa:
“Anything that improves the image of Nigerian football is something that I strive to embark on and Kano Pillars holds a special place in my heart.
“It’s the team that helped me become the professional footballer I am today, so this is more than just football but a very strong bond.”
During his first spell with Pillars, the 28-year-old scored 18 goals to finish as top scorer in the 2009/10 NPFL season.
