Tory Lanez offered Megan Thee Stallion money in return for her silence after allegedly shooting her twice in the foot ... so she claims in a new interview.

The rapper says Tory begged her to stay quiet and tried to pay both her and her friend off shortly after the July incident ... for which Lanez has been charged with felony assault.

Megan tells GQ she was really scared because what happened with Tory went down during the middle of the national unrest and protests over police brutality and systemic racism. She says her response to Tory's offer was ... "I can't believe you even think I want to take some money. Like, you just shot me."

MTS goes on to call the incident and the weeks that followed the worst experience of her life, which as we reported ... included her first coming out publicly to address rumors and speculation, and then flat out accusing Tory of pulling the trigger.

Though Lanez has been charged with felony assault for allegedly inflicting great bodily injury on Megan -- and ordered to stay away from her -- he's defended himself by saying a charge is not a conviction ... and went even further on his new album.

Several of the tracks on the album seemingly profess his innocence ... and suggest Megan is a liar.
