The story of Hazrat Ibrahim (Abraham) and his son Ismail (Ishmael) is a well-known and revered account in Islamic tradition. Here is a brief summary of the complete story:

- Hazrat Ibrahim had a dream in which he saw himself sacrificing his son Ismail.

- He believed the dream to be a command from Allah and shared it with Ismail.

- Ismail, showing his devotion to Allah, accepted the decision and encouraged his father to fulfill the command.

- Together, they traveled to Mina, near the Kaaba in Mecca, where the sacrifice was to take place.

- As they approached the designated area, Shaitan (Satan) attempted to dissuade them from carrying out the act, but they drove him away by pelting him with stones.

- Ibrahim and Ismail then proceeded to the place of sacrifice, where Ibrahim bound his son and laid him on the ground.

- Just as Ibrahim was about to slaughter Ismail, Allah intervened, replacing Ismail with a ram and declaring that the sacrifice had been fulfilled.

- Ibrahim and Ismail then returned to the Kaaba and performed a series of rituals, including the Tawaf (circumambulation) and the Sa'yee (running between two hills).

This story is commemorated annually during the Eid al-Adha (Festival of Sacrifice), which is one of the most significant Islamic holidays. The story teaches the importance of obedience, trust, and devotion to Allah, and serves as a reminder of the willingness of Ibrahim and Ismail to sacrifice everything for the sake of their faith.

Eid al-Adha

- Also known as the "Festival of Sacrifice"

- Celebrated by Muslims worldwide for three to four days

- Marks the culmination of the hajj (pilgrimage) rites at Minā, Saudi Arabia, near Mecca

- Begins on the 10th of Dhū al-Ḥijjah, the last month of the ṣalāt Islamic calendar

- Families that can afford to sacrifice a ritually acceptable animal (sheep, goat, camel, or cow) do so and then divide the flesh equally among themselves, the poor, and friends and neighbors

- A time for visiting with friends and family and exchanging gifts

- Commemorates the ransom with a ram of the biblical patriarch Ibrāhīm’s (Abraham’s) son Ismāʿīl (Ishmael)

Hajj

- One of the Five Pillars of Islam

- Refers to the pilgrimage to Mecca along with the performance of a set of religious rites

- Takes place in the month of Dhu’l-Hijjah and symbolizes the unity of the Muslim ummah

- Annually, over two million Muslims converge in Mecca, Saudi Arabia to visit the Ka’bah, the “House of God” toward which all daily ritual prayers are directed

- A required duty for all Muslims to perform at least once in their life, given they have the financial and physical capabilities of doing so

The connection between Eid al-Adha and Hajj is that Eid al-Adha marks the culmination of the Hajj rites, but they are separate events. Eid al-Adha is celebrated by Muslims worldwide, while Hajj is a pilgrimage to Mecca that takes place in the month of Dhu’l-Hijjah.
