Ar-Ra'd - 13:21

وَالَّذِينَ يَصِلُونَ مَا أَمَرَ اللّهُ بِهِ أَن يُوصَلَ وَيَخْشَوْنَ رَبَّهُمْ وَيَخَافُونَ سُوءَ الحِسَابِ
[13:21]
And those who join that which Allah has bidden to be joined and have awe of their Lord and fear the evil reckoning.
Those who join together those things which Allah hath commanded to be joined, hold their Lord in awe, and fear the terrible reckoning;
Such as unite that which Allah hath commandeth should be joined, and fear their Lord, and dread a woeful reckoning;
