What is nashukra pun? Like if I ask for something to my husband then it's unthankfulness?

No.i think you have miss understood.what quran is trying to imply by thankfulness is that every child should thank their parents as every creature/human should thank their god(for everything you have in life,for giving you eyes to see beautiness,,mouth to eat every delicious food,ears to hear every wonderful sound nose to breath,heart that beats every second of everyday,thankful for letting you wake up everyday and living your life).and Allah tells you to ask to ask Him.whatever you want ask Him and depend on Him(showing your faith that he is The All-Mighty that watches and looks after the whole universe.As for asking you husband is not unthankfullnesss.that is need.your need in life.asking for things is not Forbid by quran.
