Bismillah, Alhamdulillah, Wassalatu Wassalamu Ala Rasulullah

Abu Hurairah Radi Allahu Anhu se rivayat hai ki RasoolAllah Sallallahu Alaihi wa Sallam ne farmaya jo ye chahey ki uski Rozi bahd jaye aur uski Umar lambi ho jaye usey chahiye ki Sila-Rahmi (rishteydaron ke saath achcha suluq) karey.

Narrated Abu Huraira Radi Allahu Anhu : I heard Allah’s Apostle Sallallahu Alaihi wa Sallam 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.
[Sahih Bukhari, Vol 8, Book 73, No. 14]
