Concept:The Truce of al-Hudaybiyyah was a diplomatic peace treaty between the Muslims of Madinah and the Quraysh of Makkah in
628 CE.
Explanation:The treaty was signed at Hudaybiyyah, a village located about
9 miles outside Makkah.
It was a landmark event because it made the Muslims equal partners in negotiation with the Quraysh.
One of the key terms was that both parties would observe a truce of
10 years without fighting.
Another term was that Muslims would not enter Makkah that year, but they could return the following year for a peaceful pilgrimage.
The treaty also required the return of any Quraysh member who fled to the Muslims without the permission of his guardian.
It did not involve the payment of reparations by the Ummah.
It also did not prevent Muslims from entering Makkah for ten full years.
Thus, among the given options, the correct term is the observance of a ten-year period of peace.
Answer:B. the observance by both parties of a ten year period of peace
