Re: “true” love ?
Here is the hadees you are quoting:
Hadith - Recorded Ahmad and al-Tirmidhi. [Al-Albani says it is sahih. Al-Albani, Sahih al-Jami, vol. 1, p. 234.]
The Prophet said, "A man is never alone with a woman except that Satan is the third."
This is talking about being alone with a na mahram . Love can be nurtured without being alone. In modern days there is telephone , internet where you are not alone with a na mahram but still you can be in love.
Also there can be zero interaction and love can be there. Love an be expressed with gestures , looks without talking or any physical interaction and contact.
You lot have to come out of your old world mentality , it is not going to work in these modern times and will take people away from religion because of your extremism instead of bringing them toward religion.
