Hazrat Abu Huraira (may Allah be pleased with him) used to say: "What will be your condition when you will not be able to collect the tax of dinar and dirham?" Someone asked, "O Abu Huraira! Do you think this will also happen?" He replied, "Yes, by Him in Whose hand is the life of Abu Huraira (may Allah be pleased with him), the Noble Prophet (peace and blessings be upon him) has foretold this." People asked, "How will this happen?" He said, "The covenant of Allah and His Messenger will be broken, then Allah will harden the hearts of the dhimmis and they will withhold their wealth and riches. By Him in Whose hand is the life of Abu Huraira (may Allah be pleased with him), this will surely happen." (He said this sentence twice.)
