I am looking for the original explanation by Ibn Hajr of a hadith in Sahih al-Bukhari in which he says the following (translation):
Hafiz Ibn al-Hajr al-Asqalani says in his Fath al Bari , (in vol.4 , book of hire/ijara, page 448-449) commenting on these two narrations: “and it is evident ( from these stated narrations) that the lasting of this Islamic nation is somewhat a thousand years, this is because the age of the Jewish nation is equivalent to that of the time periods of the Christian and Muslim ages combined, and the people of transmission (ahl an naql) have agreed that the period of the Jews till the advent of Allah’s final Apostle Muhammad was more than 2000 years, and the span of the age of the Christians was 600 years from them. And also this narration points the fact about how little of the age of this world has remained.”
