What is the ruling on offering flowers between spouses, giving them to the sick, placing them in graves, and hanging them at weddings?

Exchanging gifts is Islamically desirable, especially between spouses, based on the Prophet's (PBUH) saying: "Exchange gifts, and you will love each other, and animosity will vanish." A spouse presenting the other with a gift of flowers as an expression of affection is permissible. The fact that the Companions did not exchange gifts in this specific manner does not preclude it, as the essence lies in the gift itself. It is also not prohibited simply because non-Muslims exchange them, provided the giver's intention is not to imitate disbelievers. As for giving flowers to a sick person to bring joy and optimism for recovery, there is no objection to it, and the doer will be rewarded. However, if one does so intending to imitate disbelievers, they are in great danger. Placing flowers with the deceased or inside the grave has no basis and is an innovation. As for placing fresh flowers and moist items on the grave, scholars have differed on its permissibility. Hanging flowers at weddings is Islamically permissible, provided it is not an imitation of disbelievers.
