But if they disobey you (your kinsfolk by refusing your call, or those who have newly believed by not giving up their former way of life), then say (to them): "I am free of (responsibility for) what you do."
If they disobey you say, “I am free (disassociated) from what you do!”
Al-muntakhab fi tafsir al-Qur'an al-Karim
But should they disobey you then they will have disobeyed Allah and disregarded His laws. Then say to them O Muhammad: "I am innocent of your ills and of all that you do"
