Eid al-Adha, the festival of sacrifice, is celebrated in the first week of October by Muslims around the world. The festival is also known as Barka Eid and is celebrated for four days worldwide.
Here are a few quotes from the Quran, compiled by The Eid.com, to celebrate the Eid al-Adha:
"O children of Adam, we have provided you with garments to cover your bodies, as well as for luxury. But the best garment is the garment of righteousness. These are some of GOD's signs, that they may take heed." [7:26]
"Whoever kills another one without justifiable cause, surely he is killing all of humanity. And whoever saves the life of another one, surely he saves the lives of all of humanity." Sura Al Ma'aidah: Ayah 32
"Your Lord has commanded that you worship none but Him, and be kind to parents. If either or both of them reach old age with you, do not rebuke them, but speak to them in terms of honor and kindness. Treat them with humility, and say, 'My Lord! Have mercy on them, for they did care for me when I was little'." [17:23-4]
"Those who believed and led a righteous life are the best creatures." [98:7]
"And if you punished, let your punishment be proportionate to the wrong that has been done to you; but if you show patience, that is indeed the best course." [16:126]
"If you doubt what We have revealed to Our servant, produce one chapter comparable to it. Call upon your idols to assist you, if what you say be true. But if you fail (as you are sure to fail) then guard yourselves against the Fire whose fuel is men and stones, prepared for the unbelievers." - [Quran 2:23-4]
"O ye who believe! Take not into your intimacy those outside your ranks: They will not fail to corrupt you. They only desire your ruin: Rank hatred has already appeared from their mouths: What their hearts conceal is far worse. We have made plain to you the Signs, if ye have wisdom." [3:118]
During Eid al-Adha, several Muslims travel to Mecca for the Hajj pilgrimage. The festival of sacrifice or greater Eid starts the day after Muslims on the Hajj pilgrimage descend from Mount Arafat, according to Kippreport.com.
Eid al-Adha is also referred as Eid al-Kabir, which means the Greater Feast.
As a part of the tradition, a Muslim has to recite "tusmiya" before sacrificing a sheep or a goat.
