Why does God create disable persons despite of having His judgement day –Ask Dr Zakir Naik

Prof. Tejasen accepted Islam on the strength of just one scientific “sign” mentioned in the Quran. Some people may require ten signs while some may require hundred signs to be convinced about the Divine origin of the Quran. Some would be unwilling to accept the Truth even after being shown a thousand signs. The Quran condemns such a closed mentality: Deaf, dumb and blind- so they will not return [to the right path]. (Quran, 2:18). Also: The example of those who disbelieve is like that of the one who shouts at what hears nothing but calls and cries [i.e. cattle or sheep] - deaf, dumb and blind, so they do not understand. (Quran, 2:171). And: Then do they not reflect upon the Quran, or are there locks upon [their] hearts? (Quran, 47:24).
