Relation with Kith and Kin

Narrated by Abu Huraira:I heard Allah's Apostle (peace be upon him) saying,


"Who ever is pleased that he be granted more wealth and that his lease of life be pro longed, then he should keep good relations with his Kith and kin." 

[Bukhari Vl 8, No 14] [Kith and kin mean acquaintances and relatives and family]
