Hazrat Th'alaba [ثعلبه ]Ibn abdur Rahman رضي الله عنه was a young man of sixteen, from the Ansaar. He would often run errands for Rasulullah  صلى الله عليه وسلم.

One day , whilst taking a walk in Madina Munawwarah,  he passed by a house . The door had been left open. Without much thought, and a little curious ,he glanced inside the house.

....He did not anticipate what would then transpire.

When he glanced into the house ,a breeze lifted and shifted the curtain of an entrance, revealing a woman who was taking a bath.

Hazrat Th'alaba رضي الله عنه immediately lowered his gaze , but his heart and mind were already tormented by guilt.

....He did not continue gazing. No . He immediately lowered his gaze. This was not what he expected to see.

Despite his youthfulness, look at his response. There was a Khauf and fear of Allah Ta'ala, there was shame and modesty
