Today is the day known as Good Friday, this day is observed by Christians around the world, for them it is a holy day, this is the day in which Jesus was betrayed and taken onto the cross and crucified, hence the Good Friday. Now if we are to take this date for granted, meaning that if this is indeed the exact precise date of Jesus' crucifixion, then indeed this is a Good Friday, not for the Christian reasons, but for the true Islamic reasons, because then it was on this day that God thwarted his enemies and saved his prophet and Messiah Jesus.
Just like the Christians we the Muslims believe that the crucifixion episode took place on a Friday, however so unlike the Christians we don't believe that God allowed for his Messiah to be humiliated and killed off by his enemies, we read from the Quran:
That they said (in boast), "We killed Christ Jesus the son of Mary, the Messenger of Allah";- but they killed him not, nor crucified him, but so it was made to appear to them, and those who differ therein are full of doubts, with no (certain) knowledge, but only conjecture to follow, for of a surety they killed him not:- Nay, Allah raised him up unto Himself; and Allah is Exalted in Power, Wise (4:157-158)
So as we read, Allah saved Jesus from the hands of his enemies, the evil wicked enemies of God were planning and plotting against Jesus, they did not like him nor his message, hence they wanted to get rid of him, and they also wanted to prove something to themselves as well, that by killing Jesus this would prove that he was not their king, nor Messiah, because after all the Messiah would not be killed as a criminal at the hands of his enemies. Their plot was foiled, Allah saved Jesus from both the cross, and from death, and instead of this Allah directly raised Jesus into the heavens, thereby leaving the enemies of Jesus in defeat and protecting the Messiah, and this is the real Good Friday.
What is so good about a Friday in which a prophet of God is killed by his enemies? A day in which a prophet of God is humiliated by his enemies? A day in which a prophet is tortured and beaten by his enemies? What is so good about such a day? Do we celebrate the anniversary of September 11th; do we call it good Tuesday? Do we celebrate the massacres of Sabra and Shatila? Do we celebrate acts of murder against the innocence by criminals? Of course not, there is nothing ?Good' about this Friday according to the Christian version of the crucifixion, the only Good thing about this Friday is that Islam is the truth, and it allows us to know that Jesus was not killed, rather he was saved, and this is why this is a Good Friday.
So to all the Muslims, if you have any Christian friends, then let them know the truth of what is really good about this Friday, let us make this day stand for what it truly is, which is a celebration of God's power in saving the Messiah, not a day in which people celebrate an act committed by the enemies of God!
And Allah Knows Best!
