Increase Your Sustenance, Live Longer (Hadith No. 1776)

Bismillah.
Volume 3, Book 34, Number 281:
Narrated Anas bin Malik (radiallaahu `anhu):
I heard Allah's Apostle (sallallaahu `alayhi wasallam) saying, "whoever desires an expansion in his sustenance and age, should keep good relations with his Kith and kin."
Everything from when Allaah created the Pen until the Day of Resurrection is written in al-Lawh al-Mahfooz, because when Allaah first created the Pen, He said to it: “Write.” It said: “My Lord, what should I write?” He said: “Write what is to be. So at that moment it began to write what would be until the Day of Resurrection. And it is proven from the Prophet (peace and blessings of Allaah be upon him) that when the foetus in its mother’s womb is four months old, Allaah sends an angel to breathe the soul into it and write down its provision, its lifespan and its deeds, and whether it is doomed or blessed.  
Provision is also written down and connected to its means, and it does not increase or decrease. Among those means are that man should work to seek provision, as Allaah says (interpretation of the meaning):
“He it is Who has made the earth subservient to you (i.e. easy for you to walk, to live and to do agriculture on it); so walk in the path thereof and eat of His provision. And to Him will be the Resurrection” [al-Mulk 67:15] 
Other means are:  
  • Upholding ties of kinship, such as honoring one’s parents and upholding ties with relatives.
  • Fearing Allaah (taqwa), as Allaah says (interpretation of the meaning): “And whosoever fears Allaah and keeps his duty to Him, He will make a way for him to get out (from every difficulty). And He will provide him from (sources) he never could imagine. And whosoever puts his trust in Allaah, then He will suffice him. Verily, Allaah will accomplish his purpose. Indeed Allaah has set a measure for all things” [al-Talaaq 65:2-3]
