Muslim Manners

It is recommended to gather ones friends and to feed them on returning from a journey, as the Prophet (may Allah’s peace be upon him) used to do.

Jaabir bin Abdullah (may Allah be pleased with him) related that:

Whenever the Messenger of Allah (may Allah’s peace be upon him) returned to al-Madeenah he sacrificed a camel or a cow.
[Muslim]

This food which is presented after a journey is known as al-Naqee’ah.  This hadeeth shows that feeding the Imaam, the leader or ones friends upon returning from a journey was a recommended act with the salaf [companions of the Prophet and early generations].
