And do not let those who hoard up (miserly) that which Allah has given them of His grace think that it is better for them. No, it is bad for them. That which they hoard (miserly) will be their collar on the day of resurrection, and Allahs is the heritage of the skies and the earth and Allah is informed of what you do (R 18)
“The wealth which people hoard, due to the fear of poverty and do not spend in the way of Allah (SWT) will be their collar on the day of resurrection, therefore it is not good for them but bad. Allah (SWT) does not order charity because He is poor, those who say this will be punished for their evil deeds.”
