The Muslim has five rights
حَقُّ الْمُسْلِمِ عَلَى الْمُسْلِمِ خَمْسٌ: رَدُّ السَّلَامِ، وَعِيَادَةُ الْمَرِيضِ، وَاتِّبَاعُ الْجَنَائِزِ، وَإِجَابَةُ الدَّعْوَةِ، وَتَشْمِيتُ الْعَاطِسِ
Haqqu-l-muslimi ala-l-muslimi khams: raddu-s-salam, wa iyadatu-l-marid, wa-ttiba'u-l-jana'iz, wa ijabatu-d-da'wah, wa tashmitu-l-atis.
"The Muslim has five rights upon another Muslim: returning the greeting, visiting the sick, following the funeral, accepting the invitation, and responding to the sneeze."
Narrated by Abu Hurayrah. Sahih al-Bukhari 1240, Sahih Muslim 2162
A short reflection
Five small obligations that knit the community. None are heroic. All are constant. The fabric of the masjid neighbourhood is woven from these.
