Who is closest?

Youssef, Mahmoud and Amna are three brothers.

They decide to compete with each other to be the closest.

But the closest to what? And what is the way to win this competition?

(The story aims to present the hadith of the Messenger, may God’s prayers and peace be upon him, “The closest of you to me in assembly is the best in manners” through an interesting story.)
