It is about keeping spirit of shahadat alive. Its about keeping to remind ourselves that truth will be in constant battle with the falsehood. And what better example then the sacrifice of Imam Hussain (as). As a Muslim we should be proud that such sacrifice came from nobody but the grandson and the family of our prophet!
Allama Iqbal said:
Insaan ko bedar tou ho lenay dou
Har Qaum pukaray gi humaray hein Hussain!
Jews keep holocaut alive for their own political gains and interests. We Muslims however should remember Karbala not for wordly gains but goals beyond that. We live in the world today where truth seems to be disappearing. Recalling Imam Hussains’ sacrifice serves as a reminder to all the humanity to keep battling against the opressors no matter how dire the situation or how heavy the consequences may be.
No doubt today the front fighters against the Pharoahs of today are lovers of Imam Hussain (as). Be it revoloution in Iran, victories of the Labanese resistence, Iraqi uprisings, or Hamas battle for their rights.
