Welcome to the forum Naseer -- it's really kind of hard to say unless you check out their vent on the bottom in front of the anal fin: more v-shaped indicates male; more u-shaped or oval usually indicates a female. It's not easy but see if you can get a better under-fish photo, it might help to confirm.
Sometimes having black coloration on the top dorsal fin can indicate being female, and it kind of appears in the photos that yours may be darker on the dorsal fin, but I can't see for sure and it could be due to stress of transfer/going into new home.
Also if I can see clearly in the 2nd pic, it appears the little thingy coming out of its vent is angled backwards, which they say can be another indication of being male. Finally it's already starting to get a decent hump for its size (and considering it's stressed), so my vote is with male but I could be wrong
