It was narrated from Abu Sa'eed Al-Khudri that the Prophet (ﷺ)
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.'"
