The recommendation of Imam Sajjad (peace be upon him) on the Community Rights

It is up to you to place Muslims besides yourself as your kinsmen! So, whoever was old, consider him like your father, and whoever was young, consider him as your offspring (or your children), and consider your same age as your brother. So at that time, do you want to oppress them? … And you know that the most honorable people in their viewpoint is one who does good for them, and he does not need them and one who makes chastity.
