Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "The expanse of my cistern is as much as the distance from the Ka'bah to Bayt al-Maqdis. Its water is whiter than milk, its drinking vessels are as numerous as the stars, and on the Day of Resurrection, my followers will outnumber the followers of all the other prophets."

It is narrated from Sayyiduna Thawban (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "The width of my cistern (Hawd) is from Aden to Oman. Its water is whiter than snow and sweeter than honey. The majority of those who will come to it will be the Muhajirun, who are now disheveled in hair and wearing dirty clothes. They cannot marry well-off women, closed doors are not opened for them, and they fulfill their responsibilities, but their rights are not fulfilled."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "My Ummah will come to me at the Hawd (the Pond). I will drive away some people from it just as a man drives away the camels of others from his own camels." The Companions asked: "O Messenger of Allah! Will you recognize us?" He (peace and blessings be upon him) said: "Yes, you will have a sign that no one else will have. You will come to me with your foreheads, hands, and feet shining due to the effects of ablution. But a group among you will be prevented from reaching me; they will not be able to reach (me). I will say: 'O my Lord! These are my companions?' An angel will reply to me: 'Do you know what they innovated after you (in religion)?!'"
