Mafhum-e-Hadith: Rishtedar tumhare saath buraii kare to bhi unke saath achcha suluq karo
Abu hurairah radi allahu anhu se rivayat hai ki Rasool-Allah Sal-Allahu Alaihi Wasallam se ek shaksh bola Ya Rasool-Allah sallallhu alaihe wasallam mere kuch Rishte wale hain main unse Ehsaan karta hun aur wo burai karte hain main Rishta (nata) milata hun aur wo todte hain main bardbaari ( achcha suluk) karta hun aur wo jahalat karte hain Aap Sal-Allahu Alaihi Wasallam ne farmaya ki agar haqeeqat mein tu aisa hi karta hai to tu unke munh par jalti raakh (ash) dalta hai aur hamesha Allah ki taraf se tere saath ek farishta rahega jo tumko un par ghalib rakhega jab tak tu is haalat par rahega.

Abu Huraira Radi Allahu Anhu reported that a person said: Allah’s Messenger Sal-Allahu Alaihi Wasallam said , I have relatives with whom I try, to have close relationship, but they sever (this relation). I treat them well, but they treat me ill. I am sweet to them but they are harsh towards me. Upon this he (the Holy Prophet) said: If it is so as you say, then you in fact throw hot ashes (upon their faces) and there would always remain with you on behalf of Allah (an Angel to support you) who would keep you dominant over them so long as you adhere to this (path of righteousness).
