This hadeeth comes under the following chapter: FORBIDDANCE IN CALLING ONE (OTHER THAN ALLAAH'S APOSTLE) WITH THE KUNYA OF ABU'L-QASIM AND THE FACT PERTAINING TO GOOD NAMES
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 Allaah's Messenger (sallAllaahu alayhi wa sallam) 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 Prophets and pious persons who had gone before them.
