وَٱلَّذِينَ يَصِلُونَ مَآ أَمَرَ ٱللَّهُ بِهِۦٓ أَن يُوصَلَ وَيَخْشَوْنَ رَبَّهُمْ وَيَخَافُونَ سُوٓءَ ٱلْحِسَابِ
And those who join that which Allah has ordered to be joined and fear their Lord and are afraid of the evil of [their] account,
(Such as unite that which Allah hath commanded should be joined) of kinsfolk; it is also said that this means: of the belief in Muhammad (pbuh) and in the Qur'an, (and fear their Lord) and do works for the sake of their Lord, (and dread a woeful reckoning) and fear Allah's severe chastisement.
