Salaam all,
I agree that hugging and kissings are ok if it's not leading to sexual intercourse.
But the importance in this is that the two persons must known eachother for some time, so no totally strangers.And there would be a longing to get married later on.
And don't forget about friends, they can kiss on the cheek and hug a friend of the opposite gender if it is done in a friendly way.
Don't forget about RESPECT so please ask first if it's ok to kiss a lady before u do it.
Peace
Sis Majidah
