The Driver of Families and Women
Question :
What is the ruling on a driver mixing with a family, with the women and the young girls, and going out with them to the shops and schools?
Answer:
It has been authentically reported in a Hadith that the Prophet said:
"A man does not sit alone with a woman, except that Satan makes a third."
Seclusion usually takes place in the house, the car, the market, a shop or the like.
When they are alone together, there is no guarantee that their conversation will not turn to forbidden things, or things which arouse desire. Although there exists a sense of piety in some men and women, a fear of Allah, a hatred of disobedience and breach of faith, yet, Satan interferes between them and makes it easy for them to sin. He opens the doors to lust for them, but the (righteous) servant is safer and more protected from that.
