I've met people who had "different physical" from me, I have a perfect hand, body, eyes, and everything that I need.
But I've found people who doesn't have hands, and feet, and other lack of physical need.
Some people got accident so they got injured, some people born in "Different physical".
If Allah is All Just, where is the justice in the case when people born in "Different Physical"? If people can choose when they will be born, I'm sure they don't want to be born like that.
