Mufaz'zil ibn Umar narrated that
a man came to Imam Sadiq (a.s) when Umar was also there and said: “Our ancestors believed that when God loves someone, there is a Heavenly call that announces: “God loves him, therefore you love him too”, and God makes everyone love him; and whenever God is angry with someone, there is a Heavenly call that announces: “God is angry with him and you be angry with him too”, and God makes everyone angry with him.” Then Imam Sadiq (a.s) who was leaning (on the pillow) sat up straight and shook his sleeves and said: “It is not so. When God loves someone, he will test other people by him, so others say things about him and he gets rewarded, and they commit a sin. When God is angry with someone, He will place his love in the people's heart so that they say things about him which are not right and both he and they commit a sin. Who was dearer to God than John the son of Zacharia? God excited some people against him and they killed him. Who is dearer to God than Hussein, the son of Ali (a.s)? God excited some people and they killed him. No. It is not as you say.”
