A Muslim’s way of life is that he lives and lets others live and he enjoys and lets others enjoy. We should not be concerned for ourselves only. We should have others at heart as well.
It is the capitalist system that makes one concerned of oneself only. Therefore, if there is an abundance of a food product they will be able to dump tons of that product despite the multitudes that are in need. On the contrary, the Islamic teaching is that one cannot sleep whilst his neighbour remains hungry.
Nowadays the mindset that we have is that whatever extra we have should be spent on ourselves only. We will go for ‘umrah trips and on holidays but not see to the plight of the poor. We need to prioritise ourselves.
The way of the people of the past was that they would always feed and take care of others. And this in fact is the teaching of the hadeeth where Nabi (sallallahu ‘alaihi wasallam) had encouraged feeding.
