Signifying love of the Prophet (blessings and peace of Allah be upon him) by drawing a heart
Question

There are some key chains that are made in the shape of a heart, which is a symbol of love, on which is written “I,” then the drawing of the heart, “the Prophet,” meaning: I love the Prophet (blessings and peace of Allah be upon him). On the back is written: Ya Habeebi, Ya Rasool Allah (O my Beloved, O Messenger of Allah). The other thing is a disk that is worn on the chest, which has the same things written on it. It has also become common among some women to wear women's shirts which have these phrases written on them on the left side, on the chest. What is the ruling on these things?.
Praise be to Allah.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 Allah 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 haram 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 Allah (blessings and peace of Allah be upon him) is like love for any other created being, and this is a serious error, because love for the Messenger of Allah (blessings and peace of Allah 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 haram. Based on the above, writing the phrase mentioned, buying and selling it and using it is not permissible. 
And Allah is the source of strength. May Allah send blessings and peace upon our prophet Muhammad and his family and Companions. End quote.
