You mean they weren't slaughtered as long as Muhammad's followers could subjugate them to second class status in dhimmitude, and parasitize them through the jizya tax.
Golden age under Islam?!! Gwaffaw! Jews are to Islam today, just as they were in Muhammad's day.

JESUS OR MUHAMMAD
Qur'an Surah 33:26 Allah took down the People of the Scripture Book. He cast terror into their hearts. Some you slew, and some you made prisoners. And He made you heirs of their lands, their houses, and their goods, giving you a land which you had not traversed before. And Allah has power over all things.
Tabari VIII:38 "The Messenger of Allah commanded that all of the Jewish men and boys who had reached puberty should be beheaded. Then the Prophet divided the wealth, wives, and children of the Banu Qurayza Jews among the Muslims."
Abu Dawud 38:4390 Narrated Atiyyah al-Qurazi: I was among the captives of Banu Qurayza. They (the Companions) examined us, and those who had begun to grow hair (pubes) were killed, and those who had not were not killed. I was among those who had not grown hair.
Tabari VIII:35/Ishaq:464 "The Jews were made to come down, and Allah's Messenger imprisoned them. Then the Prophet went out into the marketplace of Medina (it is still its marketplace today), and he had trenches dug in it. He sent for the Jewish men and had them beheaded in those trenches. They were brought out to him in batches. They numbered 800 to 900 boys and men."
Tabari VIII:40 "The Messenger of God commanded that furrows should be dug in the ground for the Qurayza. Then he sat down. Ali and Zubayr began cutting off their heads in his presence."
Ishaq:465 "Then the Apostle divided the property, wives, and children of the Qurayza among the Muslims. Allah's Messenger took his fifth of the booty. He made known on that day the extra shares for horses and their riders - giving the horse two shares and the rider one. A Muslim without a horse got one share of the spoil. It was the first booty in which lots were cast."
Tabari VIII:38 "The Prophet selected for himself from among the Jewish women of the Qurayza, Rayhanah bt. Amr. She became his concubine. When he predeceased her, she was still in his possession. When the Messenger of Allah took her as a captive, she showed herself averse to Islam and insisted on Judaism."
Bukhari:V5B59N459 Narrated Ibn Muhairiz: I entered the Mosque and saw Abu Said Al-Khudri and sat beside him and asked him about Al-Azl (i.e. coitus interruptus). Abu Said said, "We went out with Allah's Apostle for the Ghazwa of Banu Al-Mustaliq and we received captives from among the Arab captives and we desired women and celibacy became hard on us and we loved to do coitus interruptus."
Ishaq:480 "The Qurayza met their misfortune. In humiliation they found no helper. A calamity worse than that which fell upon the Nadir befell them. On that day Allah's Apostle came to them like a brilliant moon. We left them with blood upon them like a pool. They lay prostrate with the vultures circling round."
Ishaq:204/ Tabari VI:134 "'Men of the Khazraj, do you know what you are pledging yourselves to in swearing allegiance to this man.' 'Yes,' they answered. 'In swearing allegiance to him we are pledging ourselves to wage war against all mankind.'"
Ishaq:472 "Muhammad's Companions are the best in war."
Ishaq:475 "Allah commanded that horses should be kept for His enemy in the fight so they might vex them. We obeyed our Prophet's orders when he called us to war. When he called for violent efforts we made them. The Prophet's command is obeyed for he is truly believed. He will give us victory, glory, and a life of ease. Those who call Muhammad a liar disbelieve and go astray. They attacked our religion and would not submit."
