الْمُؤْمِنُونَ كَرَجُلٍ وَاحِدٍ. إِنِ اشْتَكَى عَيْنُهُ اشْتَكَى كُلُّهُ، وَإِنِ اشْتَكَى رَأْسُهُ اشْتَكَى كُلُّهُ
Believers are like one person. If his eye is in pain, the whole person suffers; if his head is in pain, the whole person suffers.

In كَرَجُلٍ, كَ means “like” and رَجُلٍ means “man/person”; وَاحِدٍ specifies one. The actual word is person, followed by that person’s eye and head to illustrate their bodily relationship. إِنِ means “if” and introduces a condition; distinguish it from the earlier أَنْ linking an action such as discovery.
