Praise be to Allah, and peace and blessings be upon the Messenger of Allah.
It is not valid to specify the age of the world or the date of the Day of Judgment in terms of particular years. The hadiths and reports cited in this regard are not authentically established from the Prophet ﷺ. Some are from Isra'iliyyat (reports originating from earlier religious traditions), while others are weak or fabricated.
Al-Suyuti رحمه الله held that the age of the world was seven thousand years and, based on some reports, concluded that the Day of Judgment would occur before the completion of the year 1500 AH. However, this view is not sound.
Allah تعالى says:
“They ask you about the Hour: when will it come to pass? Say: ‘Its knowledge is only with my Lord. None can reveal its time except Him.’” [Al-A'raf: 187]
And He سبحانه says:
“Its ultimate knowledge is with your Lord. You are only a warner for whoever fears it.” [An-Nazi'at: 44–45]
And Allah تعالى says:
“People ask you about the Hour. Say: ‘Its knowledge is only with Allah.’” [Al-Ahzab: 63]
These texts clearly indicate that the time of the Hour is part of the unseen knowledge that Allah has kept exclusively for Himself, and He has not disclosed it to any of His creation.
In the Hadith of Jibril, when he asked the Prophet ﷺ about the Hour, he replied:
“The one who is asked about it knows no more than the one who asks.” Narrated by Muslim.
The scholars explained that the hadiths and reports which specify the occurrence of the Hour after a particular period cannot be relied upon.
Ibn al-Qayyim رحمه الله stated that the report specifying the age of the world as seven thousand years is among the false reports, because it contradicts the clear Qur’anic principle that knowledge of the Hour belongs to Allah alone.
Ibn Kathir رحمه الله stated that no hadith has been authentically established from the Prophet ﷺ specifying the time of the Hour within a fixed period. What has been authentically established from him is his mention of its signs and portents.
Al-Sakhawi رحمه الله stated that reports specifying the exact time of the Resurrection either have no reliable basis or have an unestablished chain of transmission.
The chronological predictions attributed to al-Suyuti led to events that did not occur. Periods were specified for the emergence of the Mahdi, the appearance of the Dajjal, the descent of Isa عليه السلام, and the rising of the sun from the west. Those specified periods passed without these events occurring.
This confirms that specifying the date of the Hour or arranging its events according to unsupported chronological calculations is not valid.
The obligation is to believe in what Allah and His Messenger ﷺ have informed us about the signs of the Hour, without specifying its date or the age of the world in years for which there is no authentic evidence.
And Allah تعالى knows best.
