Stand in prayer on all parts of Mount Arafah during Hajj as an act devotion towards Allah .

The hadith narrated by Ja'far bin Muhammad states that the Prophet Muhammad (PBUH) taught that all of Arafat is the place of standing during Hajj. This means that when performing the pilgrimage to Mecca, Muslims must stand in prayer on all parts of Mount Arafah. This is an important part of the Islamic faith and a way for Muslims to show their devotion to Allah and seek His mercy and forgiveness. It also serves as a reminder for Muslims to be humble before God and strive for righteousness in their lives. Additionally, this hadith teaches us about patience and perseverance as it requires pilgrims to stand in one spot for hours at a time while they pray.
