As your faith grows, you care more about others. How does a believer see the community? Think of a parent. A parent sees his own self in his child. Just as no person wants harm for themselves, they do not want harm for their child - unless they misjudge what is good for them. This is human nature, as Imam Sadiq, peace be upon him, says: "Hearts are meant to love those who benefit them and hate those who harm them. " "Hearts naturally tend to love those who benefit them and hate those who harm them. " [read the narration here]) Now, apply this to the community of believers. When the believers' relationship with the believing community reaches a certain level, they see other believers as an extension of their own selves. They don't see them as strangers. Because they see them as their own self, they want good for them and do not want harm for them. This is why they "command what is right" (i.e. if another believer is hurt or faces a problem, they really feel it as their own hurt. The Qur'an shows this connection: "And the believing men and the believing women are allies of one another. " "The believing men and the believing women are one another's allies. "This is a connection of unity. On the other hand, regarding the hypocrites, the Koran says: "The hypocrites and the hypocrites are in each other" - there was a connection between them, but not a true unity, because there was no wilayah (guardianship). The Prophet, peace be upon him, describes this unity perfectly: “The believers are united, united and unified as if they were one soul. " "The believers are united, support each other, support each other, as if they were one soul. " [Read the narration here]) For believers, the connection reaches the level of unity.
