The best of you to your families
خَيْرُكُمْ خَيْرُكُمْ لِأَهْلِهِ، وَأَنَا خَيْرُكُمْ لِأَهْلِي
Khayrukum khayrukum li-ahlih, wa ana khayrukum li-ahli.
"The best of you are those who are best to their families, and I am the best of you to my family."
Narrated by 'A'ishah. Jami' at-Tirmidhi 3895 (sahih)
A short reflection
The character you show outside means little if the people in your home don't see it.
