Zaid bin Al-'Ammi said: "I heard Abu As-Siddiq An-Naji narrate a Hadith from Abu Sa'eed Al-Khudri who said: 'We feared events to occur after our Prophet, so we asked Allah's Prophet(s.a.w), and he said: "Indeed there will be a Mahdi who comes in my Ummah (ruling) living for five, or seven, or nine."- Zaid was the one in doubt- He said: "We said: What is that?" He said: "Years." He said: "A man will come to him and say: O Mahdi! 'Give to me, give to me! So he will fill in his garment whatever he is able to carry.'"
It was narrated from Abu Sa'eed Al-Khudri that the Prophet (s.a.w.a.) said: "The Mahdi will be among my nation. If he lives for a short period, it will be seven, and if he lives for a long period, it will be nine, during which my nation will enjoy a time of ease such as it has never enjoyed. The land will bring forth its yield and will not hold back anything, and wealth at that time will be piled up. A man will stand up and say: 'O Mahdi, give me!' He will say: 'Take.'"
