Page 383 - Hazrat Mahdi (pbuh) is a Descendant of the Prophet Abraham (pbuh)

Our Prophet (may Allah bless him and grant him peace) reveals in
his accounts that "the life span of my ummah will be 7,000 years."

The Messenger of Allah (may Allah bless him and grant him pea-
ce) stated: The life span of the world is seven days in the afterlife
days. Almighty Allah said that a day in the sight of the Lord is li-
ke a thousand of your years. (Suyuti, Al-Kashf 'an (fi) Mujawa-
zat Hadihi l-Umma al-Alf, al-Hawi lil Fatawi, p. 10.)

In another hadith, our Prophet (may Allah bless him and grant him
peace) states that 5,600 of these 7,000 years had passed up until his own
day.

Five thousand, six hundred years have passed from this
world. (Ali Ibn Husamaddin, Al-Burhan fi Alamat al-Mahdi Ak-
hir al-Zaman, p. 89.)

A calculation of 7,000-5,600 based on these dates given by our
Prophet (may Allah bless him and grant him peace) gives the 1,400. We
are now in the year 1430 [Hijri year.] (The 100 years from 1,400 to 1,500
represent the 1400s.)
