It is not haram to lead a high class or a luxurious life as the Prophet (peace and blessings be upon him) is reported to have declared, “Blessed is the lawfully gained money that is spent by a righteous person.” It is worthy mentioning here that some of the Prophet’s companions (may Allah be pleased with them all) were very rich and they used their money to help the poor and the needy.
Thus, possessing money is not an evil in itself as some may claim. But, the way this money is spent can be classified by being either lawful or unlawful. Thus, as long as one is kind to the poor and to their relatives, and they regularly pay the Zakah on their money, then there is nothing wrong to lead a luxurious life.
With this in mind, we call upon everyone leading a luxury life to stick to moderation in everything and to avoid extravagance.
They should also consider that possessing money in itself is a double-edged weapon, and thus try their best to put their money in that which is useful and beneficial for them in this life and in the Hereafter. Remember very well that money is the only thing because of which one will be brought to account twice in the Hereafter: From where you get it and to which purpose you spent it!? Thus, a Muslim should earn money from a purely halal source and spend it on that which is permissible not on that which is religiously prohibited.
Last but not least, let us contemplate on the following Qur’anic verses in which Allah Almighty says, “O ye who believe! Let not your wealth nor your children distract you from remembrance of Allah. Those who do so, they are the losers. And spend of that wherewith We have provided you before death cometh unto one of you and he saith: My Lord! If only thou wouldst reprieve me for a little while, then I would give alms and be among the righteous. But Allah reprieveth no soul when its term cometh, and Allah is Aware of what ye do.” (Al-Munafiqun 63: 9-11)
May Allah rescue us all from our evil inclinations and guide us all to the best.
