Mukhtasar Bukhari

Narrated Abu Huraira (may Allah be pleased with him) from the Prophet (peace and blessings of Allah be upon him): People will be gathered in three ways. One group will be those who will be hopeful and fearful, and (the second group) will be those who will ride two by two, three by three, four by four, and ten by ten on a single camel. And the rest of the people will be gathered by fire; wherever they rest, it will rest as well, and wherever they spend the night, it will spend the night as well, and wherever they reach the morning, it will reach the morning as well, and wherever they reach the evening, it will reach the evening as well. (That is, it will bring them to the field of gathering.)
