Muhammad Ibn Maslama and Qab's Dispensation

Muhammad ibn Maslama, one of the ways he got rich was by giving money. He had a system or routine, and everybody knows that,. That's why he is here now in Qab's office basically asking for a loan. The procedure back then still is to this day, what's your mortgage, give me a mortgage. Then Muhammad asked if he could take his sons with him until you can pay it off in a few days - they said yes. And so Muhammed offered them weapons as well: "Let we also need the money and we'll give you our weapons"
