Effect of Sins on a Relationship

We may not be too concern about our sins, that we sin everyday without remorse and regret.

Just as Anas bin Malik said:

إنكم لتعملون أعمالا هي أدق في أعينكم من الشعر إن كنا لنعدها على عهد النبي صلى الله عليه وسلم من الموبقات

"Verily you do actions that are thinner than hair in your sight, but we (the companions) in the time of the prophet used to treat them among the destructive (sins)."

[Sahih al-Bukhari]

Do not underestimate the effects of sins! Sins effect our lives and, some, directly.

One of the notable effects of sins, is its effect on human relationship.

Prophet (sallallahu 'alayhi wasallam) said:

ما تواد اثنان في الله فيفرق بينهما إلا بذنب يحدثه أحدهما

"No two people love one another for the sake of Allah, then separated except due to a sin done by one of them."
[Narrated by al-Bukhari in al-Adab al-Mufrad, authenticated by al-Albani]

So, whenever you have a quarrel with your loved ones, then check your actions. Most probably, it is because of your sins!
