When Rasulullah (sallallahu ‘alaihi wasallam) reached Busraa, he sat in the shade of a tree. A monk by the name of Nastoora lived in that area. On seeing Rasulullah (sallallahu ‘alaihi wasallam) beneath this tree, he approached him and said, “From Hazrat ‘Isa bin Maryam (‘alaihis salaam) until this moment, no prophet besides you has sat beneath this tree.” He then remarked to Maysarah, “He (Rasulullah (sallallahu ‘alaihi wasallam)) has this redness in his eyes.” Maysarah replied, “This redness never leaves his eyes.”

The monk said:

هو هو وهو نبي وهو آخر الأنبياء

“Yes, surely this is the same Prophet. This is the final Messenger of Allah Ta‘ala.”
