If they are not, he then has no share in the religion of Allah.

If they are not, he then has no share in the religion of Allah. The Prophet (S) used to say: He who believes in Allah and the Final Day should not fraternize with any disbeliever or associate with any sinful.

He whoever fraternizes with a disbeliever or associates with a sinful one is certainly regarded as disbeliever and sinful[^6].” Imam al-Baqir (a) said: My father Ali Ibn al- Hussein, once, advised me: ‘O son, do not associate, talk, or accompany five classes of people.’ ‘Who are they, father?’ asked I, and he (a) answered: ‘Beware of associating with the liar, for he is as same as mirage: he shows you the near as remote and shows you the remote as near.

Beware of associating with the sinful, for he will disappoint you for a single bite or even something less valuable. Beware of associating with the stingy, for he will let you down when you are in urgent need of his property. Beware of associating the foolish, for he harms you when he intends to do you favor.

Beware of associating with the disregardful of his relatives, for I found him cursed in the Book of Allah[^7].’ Friends should exchange expressive desires of affection and fraternity so that their handle of friendship will be firmer. But if such tendencies fade away, the relation will be enfeebled, and the alienated party will expose himself to criticism and revulsion.

Amirul-Mu'minin (a) said: “To alienate the one who desires for making friendship with you is diminution of reason, and to desire for him who does not want you is humility[^8].” Standards of Love Aspects of love may be confused among people in general and friends in particular. Suspect may creep into the relations of friendship. Solving this problem, the Ahlul-Bayt (a) identified definite mental standards that reveal the actual feelings and hidden.

Imam as-Sadiq (a) answered the man who asked him how he would realize the real feelings of those who claim bearing love towards him: “You should test your heart.

If you really love him, he will really love you[^9].” Imam al-Baqir narrated that, while he was dying, Amirul-Mu'minin (a) gathered al-Hasan, al- Hussein, Muhammad Ibn al-Hanafiyya, and the other sons and commanded them: “ Sons, you should associate with people in such a way that they will long for you when you are absent and will weep for you when you depart this life. Sons, hearts are well-mobilized troops; they recognize each other by means of amiability as well as hatred.
