Allah Screen Our Sins
Narrated Safwan bin Muhriz(R.A):
A man asked Ibn 'Umar(R.A), "What did you hear Allah's Apostle saying regarding An-Najwa (secret talk between Allah and His believing worshipper on the Day of Judgment)?"
He said, "(The Prophet said), "One of you will come close to his Lord till He will shelter him in His screen and say: Did you commit such-and-such sin? He will say, 'Yes.' Then Allah will say: Did you commit such and such sin? He will say, 'Yes.' So Allah will make him confess (all his sins) and He will say, 'I screened them (your sins) for you in the world, and today I forgive them for you."'
Well, Firstly we have to avoid taking chance of committing a sin even if we think this is just a little one, we've to avoid that on any cost but in anyway if we've done then we've to screen that from others coz If we tell others about our that doing it'll become a even bigger sin and Allah dislike that even more.
If we just screen that sin from others and ask Almighty Allah to forgive our wrong doing then Almighty Allah will also screen our sin and forgive us.
