[Abu Hafsat]

The Holy Prophet, Sallallahu alaihi Wasallam, said:--"A Muslim has six Rights over another Muslim. They (his companions) asked: What are they, O Messenger of Allah? He said:

When you meet him, greet him with peace.
When he invites you, accept his invitation.
When he seeks your advice, advise him.
When he sneezes and then praises Allah, invoke Allah's blessings upon him.
When he falls ill, visit him.
When he dies, follow his funeral. [ Sahih Muslim-2162]

When should duly keep/be observing these Rights amongst us, Muslim Brothers and Sisters, accordingly for strong and blessed Brotherhood in Islam.
Many Regards.
