Answer: No, because this is out of his/her control.
Question: So then what should such a ‘love-sick’ person do?
Answer: Be patient and earn reward.
Question: Wow! Is it possible to earn reward through unreal love?
Answer: Why not, but one must remember that even when unintentionally falling in love with someone, it is important to abide by Sharī’aĥ if he desires to earn spiritual reward. For instance, if a man unexpectedly looks at a non-Maḥram woman and despite turning his eyes away, he immediately becomes fond of her; thereafter he does not think of her deliberately nor does he look at her deliberately, nor does he meet her, talk to her on the phone or write a love letter to her or send her a gift.
In other words if he hides that unintentional involuntary unreal love so that not even a single soul knows about it, in fact, even the woman he loves does not know, and then such a ‘true lover’ dies from this love facing agonies, he is a martyr. Here is a glorious Ḥadīš of the Noble Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم, ‘Whosoever fell in love with someone and preserved his chastity and hid his love, then died in this state, died as a martyr.’ (Tārīkh-e-Baghdad, vol. 13, pp. 185, Ḥadīš 7160)
Do you see! There are conditions for a true lover: He must safeguard his chastity and hide his love, then if he dies in this love he is a martyr. In volume 1, page 859 of the 1250-page book Baĥār-e-Sharī’at published by Dawat-e-Islami’s publication department Maktaba-tul-Madīnaĥ, Ṣadr-ush-Sharī’aĥ, Badr-uṭ-Ṭarīqaĥ, ‘Allāmaĥ Maulānā Muftī Muhammad Amjad ‘Alī A’ẓamī عَـلَيْهِ رَحْـمَةُ الـلّٰـهِ الۡـقَـوِی mentioned 36 types of martyrdom, of which the 16th is: Someone who dies in love (is also a martyr) provided he preserves his chastity and conceals his love.’
