Murjiyah and Qadariyyah

Q: I have heard that RasoolAllah (sallallahu alaihi wasallam) mentioned in a Hadith that two sects i.e. the Murjiyah and the Qadariyah do not have any share in Islam due to their corrupt beliefs. The Murjiyah sect believe that a person has no control or say over his or her actions and whatever happens it is due to the Will of Allah Ta'ala and the Qadariyah sect does not believe in Taqdeer and denies it. Please clarify.

Adjusting the expiry date on a product

Q: I have purchased tomato sauce for resale; however, the tomato sauce is past the manufacturer’s best before date. I am in the food industry for the past 20 years and I know that the tomato sauce will not go bad by the date reflected by the manufacturer. In fact, the item is still good for another one year after the best before date. I wish to get the item tested by an independent food technologist and then adjust the date on the packaging to the date the independent food technologist recommends. Will it be permissible for me to adjust the date or will this fall under deception?

Correct way of washing the hands in wudhu

Q: According to the Hanafi Math-hab I'd like to know the correct way of washing the hands upto the wrists. I teach in a maktab madrassah and we used to teach them to first wash the right hand including the wrist three times and then to wash the left hand including the wrist three times but we were told that that is incorrect and it has to be as follows:

To wash both hands including the wrists three times and the action has to be done in such a way that you would alternate e.g you would first wash the right hand then the left hand and then the right hand, so the right hand would end up getting washed twice and the left once.

Can you please advise on how it should be taught to the kids.
