It is not within the character of a believer to curse, to damn, to speak or act improperly.
MuhammadWhoever wishes to be delivered from the Fire and enter the Garden should die with faith in God and the Last Day and should treat the people as he wishes to be treated by them.
MuhammadA good friend and a bad friend are like a perfume-seller and a blacksmith: The perfume-seller might give you some perfume as a gift, or you might buy some from him, or at least you might smell its fragrance. As for the blacksmith, he might singe your clothes, and at the very least you will breathe in the fumes of the furnace.
Muhammad
