Is a Sigma 50 MM f1.8 Lens compatible with Nikon F mount??

Hello There Everyone.
My name is Usman, I was wondering that Can I use a Sigma 50mm f1.8 on a Nikon??

I have tried finding a solution over the internet for the Same but I didnt get any answers telling my that I can use it on my Nikon F mount for my Nikon d5100..

(P.s. No advices for Nikkor 50MM **PLEASE**cause they are WAY toooo Expensive here in Pakistan)

Cheeers..
