Assalamu alaikum wa rahmatullahi wa barakatuhu!
In the Name of Allah, Most Gracious, Most Merciful
Do not look at those who are living a life of luxury and extravagance, for they are to be pitied, not envied. People whose only concern is to spend extravagantly on themselves and indulge in their every whim and desire and seek pleasure - whether it is permissible or forbidden - are not happy.
Rather, they are living a hard life of stress and worry, because no one who deviates from the path of Allah and disobeys Him will ever find happiness. So, do not think that those who live a life of luxury and extravagance are happy and content, not at all.
Some poor women living in mud huts are better off than those who sleep on feather beds and sheets of brocade and silk in lofty palaces, because the poor woman who believes in Allah, the Exalted, and worships Him is better off than the one who has gone astray from the path of Allah.
Happiness exists in you and you should focus your efforts on yourself.
