Sahih al-Bukhari Book 65, Hadith 264
Regarding the Verse: "And among men is he who worships Allah's as it were on the very edge."
(22.11).
A man used to come to Medina as if his wife brought a son and his mares produces offspring. He
would say, "This religion (Islam) is good," but if his wife did not give birth to a child and his mares
produced no offspring, he would say, "This religion is bad."
The Prophet (ﷺ) said, "On the day of Resurrection Allah will say, 'O Adam!' Adam will reply, 'Labbaik our Lord, and Sa`daik ' Then there will be a loud call (saying), Allah orders you to take from among your offspring a mission for the (Hell) Fire.' Adam will say, 'O Lord! Who are the mission for the (Hell) Fire?' Allah will say, 'Out of each thousand, take out 999.' At that time every pregnant female shall drop her load (have a miscarriage) and a child will have grey hair. And you shall see mankind as in a drunken state, yet not drunk, but severe will be the torment of Allah." (22.2) (When the Prophet (ﷺ) mentioned this), the people were so distressed (and afraid) that their faces got changed (in color) whereupon the Prophet (ﷺ) said, "From Gog and Magog nine-hundred ninety-nine will be taken out and one from you. You Muslims (compared to the large number of other people) will be like a black hair on the side of a white ox, or a white hair on the side of a black ox, and I hope that you will be onefourth of the people of Paradise." On that, we said, "Allahu-Akbar!" Then he said, "I hope that you will be) one-third of the people of Paradise." We again said, "Allahu-Akbar!" Then he said, "(I hope that you will be) one-half of the people of Paradise." So we said, Allahu Akbar."

(22.19) was Revealed in connection with Hamza and his two companions and `Utbah and his two companions on the day when they ease out of the battle of Badr.
