In keeping with the tradition of the Prophet Muhammad, Muslims are encouraged to prepare themselves for the occasion of Eid. Below is a list of things Muslims are recommended to do in preparation for the Eid al-Adha festival:
1. Wake up early (before sunrise).
2. Make wudu (ablution) and offer Salat al-Fajr (the pre-sunrise prayer).
3. Prepare for personal cleanliness - take care of details of clothing, etc.
4. Take a Ghusl (bath) after Fajr prayer.
5. Brush teeth (preferably with a miswak, or tooth-stick).
6. Dress up, putting on new or best clothes available (White, when available, is optimal.
7. Apply (alcohol free) perfume (attar) (men only).
8. It is customary to eat dates preferably or something before going to Eid prayers but you can't eat sacrificed meat as Sacrifice must be done after Eid prayers to be accepted as Sacrifice otherwise it becomes just normal meat and no reward for sacrifice.
9. Go to the prayer grounds (known as an 'Eidgah') early.
10. Offer Salat al-Eid (the congregational Eid prayer) in an open place, weather permitting, or in mosque.
11. Use two separate routes when travelling to and from the Eid prayer location.
12. Recite the following Takbir which starts at Maghrib (sunset) on the 9th of Dhu al-hijah and last until the Asr on the 12th Dhu al-ilhijah:
Allahu-Akbar, Allahu-Akbar, Allahu-Akbar. La ilaha illa-lah wallahu-Akbar. Allahu-Akbar wa-lillahil-hamd, which translates to: "Allah (God) is the Greatest (3 times); there is none worthy of worship except Allah, and Allah is the Greatest. Allah is the Greatest and to Him are due all praises."
Al-Quran : As-Saaffat(37) : 100 - 111
"My Lord! Grant me (offspring) from the righteous." (100)
So We gave him the glad tidings of a forbearing boy. (101)
And, when he (his son) was old enough to walk with him, he said: "O my son! I have seen in a dream that I am slaughtering you (offer you in sacrifice to Allâh), so look what you think!" He said: "O my father! Do that which you are commanded, Inshâ' Allâh (if Allâh will), you shall find me of As-Sâbirun (the patient)." (102)
Then, when they had both submitted themselves (to the Will of Allâh), and he had laid him prostrate on his forehead (or on the side of his forehead for slaughtering); (103)
And We called out to him: "O Abraham! (104)
You have fulfilled the dream!" Verily! thus do We reward the Muhsinûn (good-doers - see V.2:112). (105) Verily, that indeed was a manifest trial. (106)
And We ransomed him with a great sacrifice (i.e. کبش - a ram); (107)
And We left for him (a goodly remembrance) among the later generations. (108)
Salâmun (peace) be upon Ibrâhim (Abraham)!" (109)
Thus indeed do We reward the Muhsinûn (good-doers - see V.2:112). (110)
Verily, he was one of Our believing slaves. (111)
