On this day, society commemorates the martyrdom of the Prophet Jesus for spreading the word of Allah. It is a day that Christians and Muslims alike respect, even if the interpretation of dates and details differ.
This is a day that, like Lent, I personally find to be symbolic of the brotherhood of Islam and Christianity, sons of Abraham. For when a Shi'a thinks of the sacrifices made by those most favored by Allah, all on our behalf, how can he not think of Imam Husain AS? Chelum is almost here, and the memory of Ashara is still fresh.
Let the piety of Issa AS, and the nobility of Imam Husain AS, be a reminder to us all, irrespective of creed, of the character to which we should aspire, inshallah.
