Did any one say other wise??
The Last Hour will not come until you see the descent of ‘Isa (as) son of Maryam (as). (Muslim)
The Hour will not be established until the son of Maryam (as) (i.e. ‘Isa (as))descends amongst you as a just ruler.
(Bukhari)
At the time of his death, 'Isa (as) will have reappeared on this earth for forty years.(Abu Dawood)
The Prophet (saas) tells what ‘Isa (as) will do when he returns:
‘Isa (as), son of Maryam (as), will descend, rule for 40 years with the book of Allah and my sunnah, and die.
(Al-Muttaqi al-Hindi, Al-Burhan fi Alamat al-Mahdi Akhir al-Zaman
isa (as), son of Maryam (as), will be a just judge and just ruler (in my community), break and crush the cross and kill the pig … The earth will be so filled of peace as a vessel is filled with water. The entire world shall recite and follow one and the same Word and none shall be worshipped except Allah.
(Ibn Majah)
