Let us have compassion for those under chastisement. Alas, who are we ourselves? Who am I and who are you? Whence do we come and is it quite certain that we did nothing before we were born? This earth is not without some resemblance to a gaol. Who knows but that man is a victim of divine justice? Look closely at life. It is so constituted that one senses punishment everywhere.
Weapons are the tools of violence;all decent men detest them.Weapons are the tools of fear;a decent man will avoid themexcept in the direst necessityand, if compelled, will use themonly with the utmost restraint.Peace is his highest value.If the peace has been shattered,how can he be content?His enemies are not demons,but human beings like himself.He doesn't wish them personal harm.Nor does he rejoice in victory.How could he rejoice in victoryand delight in the slaughter of men?He enters a battle gravely,with sorrow and with great compassion,as if he were attending a funeral
Ultimately, the reason why love and compassion bring the greatest happiness is simply that our nature cherishes them above all else. The need for love lies at the very foundation of human existence.
Without religion, also there is a way, it could be this way, through education, through scientific findings, then you get conviction. Not necessarily really love other, but for their own interest they are showing love, compassion to other like that.
I have not lost Allah's hope in us to show compassion where none exists and to extend mercy in the most difficult of circumstances. We as Muslims must lead by example.
I presume that you are compassionate: to be without pity means to be sick in body and spirit. But one should have spirit in abundance, so as to be permitted to be compassionate! For your pity is detrimental to you and to everyone.
