It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that he heard the Prophet (peace and blessings be upon him) say: "My cistern (Hawd) is as large as the distance between Aden and Oman. Its water is colder than ice, sweeter than honey, and more fragrant than musk. Its drinking vessels are as numerous as the stars in the sky. Whoever drinks a single sip from it will never feel thirsty again. The first to arrive at this cistern will be the destitute emigrants." Someone asked, "O Messenger of Allah! Who are those people?" He replied: "Those with disheveled hair, sunken faces, and dirty, tattered clothes, for whom the doors of the world are not opened, whose proposals are not accepted by girls brought up in luxury, and who fulfill every responsibility but do not claim their rights."
