Final answer:
The mufti's message to Malala's family in her memoir was one of criticism, claiming her education advocacy was un-Islamic and threatening them to silence her.
Step-by-step explanation:
In the memoir I Am Malala: The Girl Who Stood Up for Education and Was Shot by the Taliban, the message the mufti delivered to Malala's family was one of criticism and danger. He expressed that Malala's actions, particularly her advocacy for girls' education, were un-Islamic, and he attempted to intimidate her family into silencing her. This reflects the larger context of the Taliban's oppressive regime, particularly regarding women's rights and education in Pakistan. The memoir by Malala Yousafzai is a powerful testament to the fight for education rights and the resistance against oppressive forces.
