English Translation
Mughira b. Shu'ba reported:When I came to Najran, they (the Christians of Najran) asked me: You read" O sister of Harun" (i. e. Hadrat Maryam) in the Qur'an, whereas Moses was born much before Jesus. When I came back to Allah's Messenger (ﷺ) I asked him about that, whereupon he said: The (people of the old age) used to give names (to their persons) after the names of Apostles and pious persons who had gone before them
