Travelling in the state of haidh

Q: My question is regarding a woman in haidh. If a woman is in haidh and she is going to travel, will the conditions of salaah apply to her? When she reaches her destination, and she becomes tahirah, will she read qasr salaah or she will first have to travel a safr distance from there in order to read qasr or will she have to count the number of days she will be staying there from the day she becomes pure inorder to read qasr? Kindly send me the reference as well.

Will the following be considered as aiding in sin?

Q: Is it haraam for me to make and sell furniture to people if I know it is more than likely that they will (at some point) be more than likely to use the furniture when doing haram things i.e. they would be more than likely to at some point store haram cloths in a closet or have unmarried adult relations on a bed I made, or use a table I made to eat pork or put alcoholic drinks on, or watch haram TV programs on the sofa I made and sold to them? Is making and selling these things cooperating in sin and transgression?

Is wasting time a sin and if so, is selling footballs or remote control cars to people cooperating, influencing sin, if I know they (adults) are going to
excessively waste time playing with them?
