As-Salaam alaikum,
The Noble Prophet, Sallallahu alaihi Wasallam, said:--
"A Muslim has 6 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].

So, let us all try to pay/respect these rights among us, Muslims, for the obvious benefits (material and spiritual) contained therein.
Many Regards.
