Signifying love of the Prophet (blessings and peace of Allaah be upon him) by drawing a heart
Making the shape mentioned and writing the phrases mentioned, on clothing, medallions and so on, is not the way of the early generations of this ummah who are the best of generations and who had greater veneration and love for the Messenger (blessings and peace of Allaah be upon him) than those who came after them. It is also an imitation of immoral people who take this symbol as a sign of their haraam love for others and who get deeply involved in this kind of love without paying any attention to rulings of sharee’ah. The shape mentioned may also be understood to mean that love for the Messenger of Allaah (blessings and peace of Allaah be upon him) is like love for any other created being, and this is a serious error, because love for the Messenger of Allaah (blessings and peace of Allaah be upon him) is an Islamic duty, without which faith cannot be complete. As for love of anyone else, it may be Islamically acceptable or it may be haraam. Based on the above, writing the phrase mentioned, buying and selling it and using it is not permissible.
And Allaah is the source of strength. May Allaah send blessings and peace upon our prophet Muhammad and his family and Companions. End quote.
