Sahih muslim says Eesa will descend and lead muslims in prayer.
Abu Hurayra (R.A) reported as Allah's messenger (Saw) as saying "The last hour will not come until the romans will land at Al- A'maq or in Dabiq.......... the time of prayer shall come and Jesus (PBUH) would descend and lead them in prayer......" (Muslim)
sahih muslim, ibn majah have recorded a narration where mahdi leads Fajr.
Eesa, son of Maryam (Mary) will descend, and their leader [i.e. the leader of Muslims] will say: “Come and lead us in the prayer.” Thereupon, ‘Eesa would say: “No, you yourselves are leaders over one another. He will say that in view of the honour that Allaah has bestowed on this Nation.” (Muslim).
My Question is the second hadith a specific case of general hadith at one. Since narration exists to prove eesa will be ruler for 40 years.
Islamqa.info says one part of revelation can make another part specific.
