Shaykh Muhammad Ibn Alee Ibn Aadam al-Etiyoobi (may Allah preserve him) mentioned a benefit from that which took place with the Prophet’s uncle Abu Taalib when he refused to say “Laa Ilaaha Illallaah”:
The beneficial love is the religious love and not the natural love. Indeed Abu Taalib used to love the Prophet with strong love. He used to give precedence to him over his own children. However, that didn’t benefit him since he didn’t love him with the legislated love which carries (a person) upon following him (i.e. the Prophet) and submitting to his legislation.
