Earning halaal

Q: There is a saying written on Pakistani notes (money): رزق حلال کمانا عین عبادت ہے

Is this a hadeeth? Does that mean that one should respect money i.e. not throw it on the floor, etc.?

Phone Contracts

Q: What is the position of a phone contract in Islam? Is it regarded as a sale or ijaarah (hire) as one is buying a phone and also paying for minutes, data, and SMS?

Sometimes, if the person doesn’t use all the minutes, he will lose the remainder and it will not carry over to the next month. Are such contracts permissible?

Meaning of breaking family ties

Q: I would like to know what does it mean to maintain and break family ties. Does it mean visiting the person? I don't visit them and we don't speak very often but when we do we greet and speak. They have hurt my feelings many times, I don't hold any grudge against them but I don't want to confide and spend too much time with them, does this mean I am breaking ties with them?
