It is narrated from Imam Sajjad (AS) who said: The sins which change blessings are:

violating people’s rights, abandoning good habits and deeds, not appreciating Divine Blessings and abandoning giving thanks (to God for Divine Blessings). Because Allah (SWT) said: “God does not change the fate/destiny of any nation unless they change their behaviours [1].”
