They summoned their slave, ‘Addaas, and said, “Place some grapes on a platter and take it to that man (referring to Rasulullah (sallallahu ‘alaihi wasallam)). Request him to please partake of the grapes.” Accordingly, ‘Addaas presented the platter of grapes to Rasulullah (sallallahu ‘alaihi wasallam).

Rasulullah (sallallahu ‘alaihi wasallam) then recited bismillah and commenced eating the grapes. When ‘Addaas heard Rasulullah (sallallahu ‘alaihi wasallam) take the name of Allah Ta‘ala, he exclaimed, “By Allah! No person in this city speaks words such as these!” Rasulullah (sallallahu ‘alaihi wasallam) then asked ‘Addaas, “Which city are you from, and what religion do you follow?” ‘Addaas replied, “I come from the city Neenway and I follow the Christian religion.”

Rasulullah (sallallahu ‘alaihi wasallam) asked, “Are you from the same city of Neenway in which the pious servant of Allah Ta‘ala, Nabi Yunus bin Mattaa (‘alaihis salaam), used to reside?” ‘Addaas was quite surprised and asked Rasulullah (sallallahu ‘alaihi wasallam), “What do you know of Nabi Yunus bin Mattaa (‘alaihis salaam)?” Rasulullah (sallallahu ‘alaihi wasallam) responded, “He was my brother, a prophet of Allah Ta‘ala, and I am also a prophet of Allah Ta‘ala.”

Hearing this, ‘Addaas immediately kissed the blessed feet, hands and forehead of Rasulullah (sallallahu ‘alaihi wasallam) and accepted Islam testifying, “I bear witness that you are the servant and Rasul of Allah Ta‘ala!” When ‘Addaas thereafter returned to ‘Utbah and Shaibah, they asked him, “Why did you kiss the hands and feet of that man? Be careful that he does not cause you to leave your religion! Remember that your religion is better than his religion.”

Hazrat Hakeem bin Hizaam (radhiyallahu ‘anhu) reports that when ‘Utbah and Shaibah were preparing to march to Badr with the Quraish of Makkah, then ‘Addaas held onto their feet and pleaded with them saying, “By Allah! He is the Rasul of Allah (sallallahu ‘alaihi wasallam)! These people are being taken to their death!”

Thereafter, as ‘Addaas sat and wept, ‘Aas bin Shaibah passed by. When he asked ‘Addaas why he was weeping, ‘Addaas replied, “I am weeping for my two masters who are now going out in opposition of the Rasul of Allah (sallallahu ‘alaihi wasallam).” ‘Aas bin Waa’il asked, “Is he really the Rasul of Allah?” ‘Addaas said, “Yes, most certainly! By Allah, he has been sent as the Rasul of Allah to the entire world.”
