As for the genocide and sacking of the Banu Qurayza tribe it's talked about in the Quran and Sira literature, as well as scattered isnad chains throughout the hadith.
In a nutshell, Abu Qasim pissed off the Meccans and they grow fearful of his growing power and influence after he relocated in Medina. Abu Qasim hires bandits and various bedouin tribes to protect the city, and takes on the help of his counins the Banu Qurayza, who were native Arabic converts to Judiasm.
They had a keep within Medina, and held off the Meccans on their own for almost a month in "The Battle of the Trench", but eventually a sandstorm forced the Meccans to retreat, ending the 30 day siege.
However Muhammad was pissed that there was no booty, and decided to turn on his Bany Qurayza allies. Another half month of siege and they surrendered. He beheaded every man and adolescent boy, took Rhianna (the chieftains wife) as his personal sex slave, and sold the women and children of the tribe into servitude.
