Salamah ibn Salamah ibn Waqsh (RA), a man from the Ansaar, was one of the Muslim participants in the Battle of Badr. He said, “We had a Jewish neighbour who lived among the clan of Banu Abd-Al-Ashhal (which was an idol worshipping clan). Just prior to the advent of the Prophet(SAWS), this neighbour left his house, came out to us, and sat in the gathering of Abd-Al-Ashhal. That day, I was the youngest person in the gathering. Upon me was a robe, within which I was lying down in the courtyard of my family. He (the Jew) mentioned resurrection, the Day of Resurrection, the accountability, the Scale, Paradise, and the Hell Fire. He was speaking to speaking to people who were polytheists and idol worshippers, people who didn’t believe in resurrection after death (here, he is speaking about his own clan, the Banu Abd-Al-Ashhal clan). they said to him,’Woe upon you, O so and so. You really feel that people will be resurrected after death to an abode that contains in it a Garden and a Fire? And do you really believe that, in that abode, they will be rewarded for their deeds?’ He said, ‘Yes, in Whose name oaths are taken, I believe this.’ He the said that, in the place of having his share of that Fire, he wished to enter the greatest oven on Earth after it is first heated and before it is then closed upon him. That is how badly he wanted to be saved from that Fire tomorrow. They said to him, ‘Woe unto you, and what is the sign of that happening?’ He said, ‘A prophet(SAWS) will be sent in the direction of these lands.’ And he pointed towards Makkah and Yemen.’ They asked, ‘And when will we see him.’ The Jewish man looked at me – and I was one of the youngest people among them- and said, ‘When this boy exhausts his years, he will be around when that Prophet(SAWS) is sent.’ By Allah, the days and nights did not depart (for me) until Allah sent His Messenger(SAWS), who was alive in our midst. We believed in Him(SAWS), but that very same Jewish man disbelieved in Him(SAWS), out of jealousy and as a form of transgression. We said to him, ‘Woe upon you, O so and so. Were you not the one who said about Him(SAWS) what you said.’ He said, ‘Yes, but that is not him.’”
