Question: How might love for the prophets and saints be without benefit?
The Answer: In the same way that the love of the Christians for Jesus (Peace be upon him), and the heretics for 'Ali (May God be pleased with him) remain without benefit. If that love is in the form that the Qur'an directs, for God Almighty's sake and in the name of the All-Merciful One's love, then it has favourable results both in this world and in the hereafter.
Now, to return to our subject, the results in this world of your love for delicious foods and luscious fruits will be that they are a pain-free bounty and a pleasure that is the essence of gratitude.
Your love of your instinctual soul. The result will be pity it, to train it, and to prevent harmful desires. Then the soul will not ride you, it will not make you a prisoner of its desires, rather, you will ride it. You will drive your soul, not to whims and fancies, but to right-guidance.
Your love for your wife. Since it will be built on her being a mine of tenderness, a gift of compassion and on her fineness of character, if you have sincere love and affection for her, she too will have earnest love and respect for you. As the two of you approach old age these sentiments will increase, you will pass your life happily. But if it is otherwise, if it is love of a pretty face and for the sake of the instinctual soul, then that love will be quickly destroyed and so too will be good relations.
Your love for your father and mother. Since it will be for God
Almighty's sake, it will be both worship and the older they grow the more your love and respect for them will increase. If you earnestly desire and pray, with the noblest of sentiments and most manly zeal, that they will live far into old age, and even kiss their hands with sincere respect and say, "Let me gain even more reward on their account", it will obtain for you a most elevated pleasure of the spirit. But if it is otherwise, and for the sake of the soul and this world, when they grow old and approach the time of becoming a burden for you, if you show them, with the most base and despicable sentiment, that they are a nuisance and then wish for the deaths of those respected people, who were the cause of your life, it will be savage and grievous pain for the spirit.
Your love for your children. As for love for those lovable, friendly creatures whom God Almighty entrusts to your supervision and upbringing, it will be a most happy love, a most happy bounty. Neither shall you suffer too much pain at their misfortunes, nor shall you cry out with despair at their deaths. As was stated above you will say, "Since their Creator is both All-Wise and Compassionate, as far as they are concerned, that death is happiness." Moreover, concerning yourself, you will think of the mercifulness of the One Who gave them to you and you will be saved from the pain of separation.
Your love for your friends. Since it is for God's sake, because separation from those friends, and even their deaths, will not be an obstacle to your conversing and your brotherhood, you will benefit from that immaterial love and relation of the spirit. And the pleasure of meeting will be permanent. If it is not for the sake of God, the pleasure of one day's meeting will result in the pain of a hundred days' separation.40

40. One second's meeting for God's sake is a year. Whereas, if it is for the sake of this world, a year is a second.
