Brotherhood in Islam means an emotional and faith-based bond between Muslims, which is formed based on religious commonalities and shared beliefs. This concept goes beyond kinship and lineage and is emphasized as a moral, social, and political principle in Islam.

This hadith by Imam Ali (as) highlights the qualities of a true and loyal friend or brother. It emphasizes the importance of standing by someone during times of hardship, offering unwavering support and care. A true brother, as described by Imam Ali, is someone who remains attentive and considerate, even when you make mistakes or face challenges, ensuring their presence and loyalty are constant.

Moreover, such a person is trustworthy and honest, providing sincere advice when you seek their guidance, without misleading or deceiving you. This profound teaching serves as a reminder of the value of genuine relationships built on trust, loyalty, and mutual care.

Key elements explained about a true and loyal brother include:

- “Does not abandon you in difficulty”: This reflects loyalty and support during tough times.

- “Does not forget you at the time of trouble/jarirah”: This implies continued care and understanding, even when the person might be at fault or experiencing negative consequences. It’s about not turning a blind eye or abandoning someone when they're in a predicament.

- “Does not cheat you when you seek his advice”: This emphasizes honesty, sincerity, and trustworthiness in providing counsel.
