Is it permissible for a pilgrim to fast while performing Hajj?

It is permissible for the pilgrim to observe voluntary fasting during the first ten days of Dhul-Hijjah and the days preceding them. However, it is recommended for him to break his fast on the Day of Arafah to gain strength for supplication. Fasting on the tenth day is forbidden for both the pilgrim and others. As for the three days of fasting obligatory for those who cannot offer a sacrificial animal during Hajj, some scholars have permitted observing them during the Days of Tashreeq (the 11th, 12th, and 13th days of Dhul-Hijjah).
