Informing the customers regarding the approximate thickness of the commodity

Q: I wanted to find out a fatwa regarding weights and measures in my business. 

We are steel traders. We buy steel a certain thickness say 0.2mm but the factories that produce it can’t get the exact thickness due to the production process. So the thickness varies from 0.195 to 0.205mm, sometimes more sometimes less. 

What is the ruling on this because we sell the product as 0.2mm. We sell as per the thickness that we order. We don’t order a lower thickness and sell as a higher thickness. This is purely a production tolerance level as the machines can never get it exact.

Using guesswork and speculation in one's life

Q: Is guesswork and speculation considered kufr if one doesn't claim knowledge of the unseen? 

Examples: 

1. A call comes to the phone, I haven't looked at it, and I speculate it's surely x person with very much confidence and it turns out to be them. And I say "look I knew it"(meaning I am so smart that I guessed it correctly not claiming knowing unseen). 

2. In multiple choice type questions choosing any of the answers blindly. Hoping you'd be correct. You don't know the correct answer and you choosing the answer was blind. Like betting. 

3. Someone asks you to guess what's in their hand and you guess. 

4. Saying a particular fictional story would probably end like the person is expecting. 

In short, is speculation and guesswork in which you have strong confidence that you are right and the one in which you don't have it. Is it considered kufr?

1. Is it permissible for him to use and drive the car?

Repeating the salaah performed with a bleeding mouth

Q: Please assist in the scenario below: 

I went for a tooth extraction at 16H15 (Asr time sets in at 16H00 but I had not yet performed Asr). Just before Asr time ended I made Wudhu and prayed Asr with blood still coming out. The blood stopped during the time of Maghrib, so Maghrib Salah was no issue. 

My question is if I have to repeat Asr as I was not yet a Mazoor (as the bleeding was not found for a complete Salaah time) but I had to pray Asr with my mouth bleeding as time was running out.
