The Rights of One Muslim Over Another

The believers are brothers and are an integrated nation, like a building parts of which support other parts. They treat one another with mercy and compassion, and love one another. In order to preserve this building and this brotherhood, Allah has prescribed rights which each Muslim has over his fellow Muslim. These include love, sincerity (naseehah), relieving his distress, concealing his mistakes, supporting him when he is in the right, respecting neighbours and honouring guests.
These rights also include returning greetings of salaam, visiting the sick, accepting invitations, saying “yarhamuk Allaah (may Allah have mercy on you) to a Muslim when he sneezes, and attending his funeral.

The Prophet (peace and blessings of Allah be upon him) said:

“The rights of one Muslim over another are five: returning the greeting of salaam, saying ‘yarhamuk Allaah (may Allah have mercy on you)’ when he sneezes, accepting invitations, visiting the sick and attending funerals.”

(Narrated by Muslim, 2625)
