First Ten Days

The first ten days of Zulhijjah are among the most magnificent days in Islamic calendar. The Holy Prophet, Sall-Allahu alayhi wa sallam, has said, "One fast during these days is equal to the fasting of one complete year, and the worship of one night during this period is equal to the worship in the "Lailatul-Qadr".

Every Muslim should avail of this wonderful opportunity by performing during this period as much Iba'dah (acts of worship) to Allah as he or she can.

The Fast of Youmul 'Arafah

For those not performing hajj, it is mustahabb (desirable) to fast on this day according to their own calendar. It sometimes occurs that 9th Zuihijjah falls on different days in different countries according to the sighting of the moon. In such cases, Muslims of each country should observe 'Youmul 'Arafah according to the lunar dates of their own country.

For example, if 'Youmul 'Arafah' is being observed in Saudi Arabia on Friday, and in Pakistan on Saturday, Pakistani Muslims should treat Saturday as 'Youmul 'Arafah' and should fast on that day if they desire to benefit from the fast of 'Youmul'Arafah'.

The fast of 'Youmul 'Arafah' has been emphasized by the Holy Prophet, Sall-Allahu alayhi wa sallam, as a mustahabb (desirable) act. According to a hadith, the fast of this day becomes a cause, hopefully so, of forgiveness for sins committed in one year.
