Bahira was a monk in the time of the Messenger of Allah ﷺ who spent his days and nights in worship. When Rasulallah ﷺ was 12 years old, he went to Shaam with his uncle Abu Talib. When Bahira saw the Prophet ﷺ he did something that he had never done. He left his area of worship, took hold of the Prophet's ﷺ hand and said, 'This is the master of man and jinn! This is the Messenger of the Lord of the worlds!"
The elderly of Quraysh asked him how he knew so he said, 'When you people came along from the road, not a rock nor a tree was left, except that it prostrated, and they do not prostrate except for a Prophet. And I can recognise him by the seal of the Prophethood which is below his shoulder blade, like an apple.' He then invited them for a meal and saw the clouds shading the Prophet ﷺ whilst he walked and the shade of trees turning towards him to keep him cool. After this meeting, the monk told Abu Talib to send Rasulallah ﷺ back to Makkah because the Romans would surely try to kill him out of jealousy. Our birth was not like his blessed birth. Our childhood was not like his blessed childhood. And our life was not like his blessed life. His greatness is beyond all comprehension. Peace and blessings be upon our Master Muhammad ﷺ ❤️
