They have no regard for either a tie of kinship or a covenant in respect of a Muslim, and they are the people who have exceeded limits (in disobedience)
They observe neither treaty nor covenant where believers are concerned! They are the very transgressors!
Sayyed Abbas Sadr-Ameli
They observe towards a believer neither ties of relationship nor treaty, and these are they who are the transgressors
Al-muntakhab fi tafsir al-Qur'an al-Karim
If they get an advantage over a Muslim and prevail against him, they shall injure him, disregarding totally their ties of kinship and their obligations. Their disposition reflects their transgressive infirmities. They prevail themselves of what the occasion gives
In (the case of) a believer they neither have regard for ties of relationship nor (their) responsibility of a pact and those are the ones who exceed the limits.
