Q: I have a question regarding kaffarah for accidentally killing someone. I read a recent post of yours saying that you have to fast for two months consecutively.

My question is, does one start fasting from the first of the month (so, assuming we follow the hijri calendar, fasting could be for 58-60 days if there are 29/30 days in the month) or can one start anytime and fast for 60 days?

Q: There are softwares that require us to meet a certain requirement in order to use them. For example, one such software can be downloaded for free, but after a 30-day trial the software asks questions like "How often did you travel by airplane last year?" If we select the "more than 2 times" option, the software stops working and we have to uninstall it. However, if we choose the option "less than 3 times," it lets us continue its use.

1. Will it be permissible to use the software if we select that we flew less than 3 times even though if we did not?

2. If someone other than the user, who did fly less than 3 times, selects that option, can the user continue the software's use? There are websites which have a pop-up that comes up, asking us to subscribe to the website. If we don't want to subscribe, we can close the pop-up by clicking on sentences like "Not yet, I'll subscribe later," or, "No, I don't like to learn."

3. If I don't intend to ever subscribe to the website, then would clicking on these types of sentences to make the pop-up go away be permissible?

4. Would it be a lie?
