1. Brothers don’t necessarily have to say anything to each other – they can sit in a room and be together and just be completely comfortable with each other
2. Nothing prevents one from going home to one’s family except prayer.
3. It starts in the home. If the father is not in the home, the boy will find a father in the streets. I saw it in my generation and every generation before me, and every one since
4. "A Muslim does not regularly attend the mosques to perform prayer and remember Allah, but Allah feels happy with him just as the family of one who is absent feels happy when he comes back to them."
[Sunan Ibn Majah 800]
