The biggest and smallest sins in Islam are those sins which might be forgivable or might not be. Shirk is the biggest sin. Shirk means associating partners to the Almighty.
The Greatest Lord of the Worlds is One and only Allah the Almighty. He knows what you reveal and whatever you conceal. He’s always watching you and so you need to remember Him and glorify His greatness. He’s the most merciful and the Omnipotent.
He has full rights over all that He created and He created everything in the Worlds. He created Mankind, Angels, Jinn, Satan, Animals, Birds and all that exists and that exists not. Glory be to Allah the Almighty.
When you commit a sin then it will be counted as one sin. When you do a single good deed then it will have not a single reward. And for that one good deed you get lots of rewards.
A Muslim submits his or her will to the Almighty and is very thankful person to Allah for his or her entire life. Mankind is created very weak and best known to commit biggest and smallest sins easily. But he’s the best Creation of the Almighty. And Allah says him or her as Ashraful-Makhlukhaat (Better than all living beings).
Biggest and Smallest Sins for example:
Shirk is an unforgivable sin. If you die in a state of Shirk and even if your children pray for you then you’ll not be forgiven. You’ve to repent and seek for forgiveness from Allah after you realize that you’ve committed Shirk. Associating partners to the Almighty is the biggest sin and it’s called as Shirk. If you die in a state of Shirk then you’ll taste the dwelling in hell fire forever.
Next big sins are: Backbiting, Zina, betraying, stealing, speaking lie, murder, suicide, alcoholism and killing innocents in war. Zina is seeking sexual pleasure other than your wife.
The biggest and smallest sins are all forgiven as the mercy of the Almighty is bigger than your sins. However, Muslims need to keep away from all biggest and smallest sins. Smallest sins are laughing loudly, disturbing people while they’re busy in their conversations. You cannot wish people suddenly when you find them communicating with each other. Talking too much is also a sin. And the more biggest and smallest sins you do the more you’ll be in trouble.
Performing prayers at five allotted times can cleanse you from your sins as the river does to a person. It’s like you’re taking bath in a river frequently or on five times then you’ll find yourself clean. So, worship the Almighty as much as possible and seek for His forgiveness. Be nice to every human being and be polite with all. Show your best character as the best Muslim and try to deliver the peaceful message of Islam.
