Musnad Ahmad Hadith 22367

Umar bin Abdul Aziz, may Allah have mercy on him, once sent a message through a courier to Abu Salam Habashi, may Allah have mercy on him. He wanted to ask Abu Salam about the Hawd (Pond) of Kawthar. So he came. Umar bin Abdul Aziz, may Allah have mercy on him, asked him about it. He said, "I heard this hadith from Thawban, may Allah be pleased with him, that I heard the Prophet Muhammad, peace and blessings be upon him, say: 'The length and width of my Hawd is as much as the distance between Aden and Amman Balqa. Its water will be whiter than milk and sweeter than honey. Its cups will be as numerous as the stars in the sky. Whoever drinks a sip from it will never feel thirsty again. The first to come to this Hawd will be the poor Muhajireen.' Umar Farooq, may Allah be pleased with him, upon hearing this, submitted in the court of the Prophet, 'O Messenger of Allah! Who will those people be?' The Prophet Muhammad, peace and blessings be upon him, replied, 'They will be those whose hair is disheveled and whose clothes are dirty, who could not marry women brought up in luxury, and for whom closed doors are not opened.' Umar bin Abdul Aziz, may Allah have mercy on him, upon hearing this, said, 'I have married women brought up in luxury, and closed doors are opened for me. Now only Allah can have mercy on me. By Allah, from now on I will not apply oil to my head until it becomes disheveled, and I will not wash the clothes I wear on my body until they become dirty.'"
