@UmerQureshi sir as you said in this answer if pleasing parents is done to show off to parents.
you meant like showing off to others that this deed of pleasing parents was done to seek Allah’s pleasure. so making a show off that it was done to achieve Allah’s pleasure, this would be shirkiya behavior right? as because trying to achieve Allah’s pleasure (which is actually humbling oneself towards Allah) should be for Allah and Allah only. but if by that humbling towards Allah, a man intends to gain people pleasure that they say ohh look how pious he is then it would be Shirk right?
But on the other hand if someone does an act of pleasing his father or mother, because his uncle said that if you do such and such thing to your father I’ll gift you something. so at that particular time and moment, he did that particular action to please his father to receive gift from his uncle. now here uncle also knows that he did not do it for Allah’s pleasure. and neither is not projecting that he did it for Allah’s pleasure. he totally says and accepts that I did for gift, so hence there’s no question of projecting piety here. but in this case it won’t be shirk, or Riya, because he didn’t take gift on trying to please Allah (through pleasing parents) rather wanted gift on just the act of pleasing parents. am I right sir?
another example of this comparison would be, a man feeds a cat so that the owner thinks that this person fed the cat for pleasure of Allah and that he is pious, this is shirkiya behavior because he uses projection of his piety (piety is only for Allah) to impress him. but on the other hand if he feeds the cat so that owner of cat knows that the man fed his cat, as a way to start of friendship with owner, so the owner feels happy with this gesture of respect and they start a friendship, this thing is totally okay. because nothing which is only and only for Allah (worship of Allah,piety, trying to fulfill a command of Allah etc) , is done or shown ir projected to please someone else, am I right sir?
