Most Beloved to the Holy Prophet (sa) from amongst the Men

Jumai bin Umair states, “I went to Hazrat Aisha (ra) with my aunt, who asked her, ‘Who was the most beloved to the Holy Prophet (sa)?’ to which she replied, ‘Fatimah’. She then asked, ‘And who was it from among the men?’ Hazrat Aisha (ra) replied, ‘Her husband, Hazrat Ali (ra)’.
