A Dilemma While Praying
This is not an occasion to feel guilty. This is human. There is no demand from God to look for sacrifices when there is no need. Look at it the other way round. Adding a comfort makes you spend more time in the presence of God and you feel grateful for having more comforts. This is the required behaviour of gratitude. Read the account of the prophet Sulaiman in the Quran. How he reacted to the blessings of God upon him, that his gratitude increases with the increase in blessing. All comforts become blessings when we do no misuse them and these do not make us arrogant or make us forget God.
