(95) باب كَوْنِ هَذِهِ الأُمَّةِ نِصْفَ أَهْلِ الْجَنَّةِ
Abdullah b. Mas'ud reported:
The Messenger of Allah (ﷺ) addressing us said: Aren't you pleased that you should constitute one-fourth of the inhabitants of Paradise? He (the narrator) said: We glorified (our Lord, i. e. we called aloud Allah-o Akbar, Allah is the Greatest). He, then, again said: Aren't you pleased that you should constitute one-third of the inhabitants of Paradise? He (the narrator) said: We glorified (our Lord) and he (the Holy Prophet) then again said: I hope that you would constitute half of the inhabitants of Paradise and I shall explain to you its (reason). The believers among the unbelievers would not be more than a white hair on (the body of a) black ox or a black hair on (the body of a) white ox.
