Ones Amity for Another is a Proof of Reciprocity

Imam Ali (AS) said, ‘Ask your hearts about their amities, for they are witnesses that take no bribes.

Imam al-Baqir (AS) said, ‘Know the amity that your brother has for you in his heart through what you harbour of the same in your own heart.

Imam al-Hadi (AS) said, ‘Do not seek sincere amity from a man you have insincere sentiment for, nor honest advice from someone you direct your distrust towards, for anothers feelings [lit. heart] towards you are similar to your feelings towards him.
