Like One Body
Nu’man bin Bashir (radi Allahu anhum) reported that the Messenger of Allah (sal Allahu alaihi wa sallam) said, “The believers in their mutual kindness, compassion and sympathy are just like one body. When one of the limbs suffers, the whole body responds to it with wakefulness and fever.”
[Sahih al-Bukhari and Muslim]
This Hadith has the same purport which is mentioned in the HaD-632. It says that Muslims are akin to a living person. When he feels pain in one of his eyes, for example, his entire body feels it. When he suffers from a headache, he feels its pain throughout his body. As a result the whole body focuses to repair any deficiencies.
That is how the Muslims should be, we should live as though we are one body and if one of us is in need then the whole community should get behind them to bring them back on their feet.
And Allah Knows Best!
