Allah (swt) says in the Holy Quran: “And give to the near of kin his due and (to) the needy and the wayfarer, and do not squander wastefully.” (TMQ-17:26)
This Quranic verse implies that the close relatives, the needy and the travelers should be paid their due rights without reminding them about one’s generosity. It would be a sin to remind them about the help provided to them because Allah (swt) has placed in every rich person’s wealth a share for the needy. If a rich person does not give the poor their due share then he would be robbing them of their rights and hence, committing a grave sin. By giving charity to the poor the wealthy people do not oblige them in any way. The word ‘relatives’ has been mentioned before the needy and the travelers which implies that at the time of giving charity one’s close relatives should be given the first preference. Paying the relatives their due and behaving well with them has been strongly emphasized in Islam. This verse ends with the advice from Allah (swt) to the people that they should abstain from wasting their wealth.
Allah (swt) says in the Holy Quran: “Indeed the wasteful are the brothers of the devils and ever has Satan been ungrateful to his lord.” (TMQ-17:27)
This verse states that the people who are spendthrift are the brothers of the Satan. Such people indulge in wasteful expenditure in order to show off their wealth. They have been described as Satan’s brother because Satan wishes to spread enmity and hatred amongst the people. If the rich people will not give the poor their due share, this apathy on their part will widen the gap between the rich and the poor and this will create hatred in the hearts of the poor.
