Are there any such narration in which the Holy Prophetﷺ said that Islam will last for 1500 years? Are there any reference to this narration?
الجواب حامدا و مصلیا
There isn’t any narration of the Holy Prophetﷺ in any of the authentic books of Ahadith, in which it is mentioned that Islam will last for 1500 years. However, in Kanz-al-Ummal (کنز العمال) and other books, it has been narrated by Ibn Abbasؓ about the duration of this world, but the scholars of Hadith have deemed such narrations to be fabricated and made-up.
And Allah knows best.
