The Treaty of Hudaibiyah
He was also amongst the companions who travelled at the time of the Sulah [treaty of] Hudaibiya. Hazrat Mirza Bashir Ahmad Sahib has written the details of this account.
“The Holy Prophet (sa) departed from Medina on a Monday morning in the beginning of Dhul Qa‘dah 6 A.H. with a group of just over 1400 companions. During this journey, Hazrat Umme Salma, the honourable wife of the Holy Prophet (sa), rode alongside the Holy Prophet (sa). Numailah bin Abdullah was appointed the Amir of Medina and Abdullah bin Umme Maktum who was a blind man, was appointed Imamus-Salat [to lead the congregational prayer].
“When the Holy Prophet (sa) reached Dhul-Halifah, which is situated approximately 6 miles from Medina en-route to Mecca, he ordered everyone to stop. After offering the Zuhr prayer, he instructed that the sacrificial camels which totalled seventy in number, be marked and that the Companions assume the special attire of the pilgrims known as Ihram. The Holy Prophet (sa) also assumed the Ihram himself as well. Then, in order to ensure that the Quraish were not up to mischief, the Holy Prophet (sa) sent ahead a messenger named Busr bin Sufyan from the Khuza‘ah tribe, who lived near Mecca and slowly proceeded towards Mecca. Moreover, as further caution the Holy Prophet (sa) appointed a cavalry of 20 riders under the command of Abbad bin Bishr, to travel ahead of the larger body of Muslims. After a journey of a few days, when the Holy Prophet (sa) neared a place called Usfan, which is situated at approximately two day’s journey on the road to Mecca, the messenger of the Holy Prophet (sa) informed him that the Quraish were furious and firmly determined to stop him to the extent that in the expression of their rage and barbarity, they had put on cheetah skins and were fully bent on war, in order to stop the Muslims in all instances. It was also ascertained that the Quraish had sent forth a cavalry unit of a few daring riders under the command of Khalid bin Walid who had not yet become Muslim, and that this cavalry had reached near the Muslims and that Ikrimah bin Abi Jahl was also a part of it.
“When the Holy Prophet (sa) heard this news, he instructed the companions to divert from the known route to Mecca and proceed from the right in order to prevent conflict. So, the Muslims began to move forward from a very difficult and burdensome route near the coast and began to move forward.”
(Seerat Khatam-un-Nabiyeen, Hazrat Mirza Bashir Ahmad Sahib (ra), pp. 749-750)
It was here where the incident of the Treaty of Hudaibiya took place. And so, Hazrat Abbad bin Bishr was amongst the cavalry which was sent to gather information. He was a very trustworthy and reliable companion. The Holy Prophet (sa) had great trust in him. He is among the companions who took part in the oath of allegiance taken at Hudaibiya which is known as Bait-e-Rizwan.
