This is another article in the chapter Enormities from the classical manual on Sharia called Reliance of the Traveller. The articles are posted one by one in the order they are given in the book.
p70.0 BRANDING AN ANIMAL’S FACE
p70.1 The Prophet (Allah bless him and give him peace) passed by a donkey whose face had been branded and said, “Haven’t you heard that I have cursed whoever brands or strikes the faces of livestock?” -and he forbade it.
p70.2 The words of the Prophet (Allah bless him and give him peace) “Haven’t you heard that I have cursed … ” imply that he who has not heard the warning against an act is not guilty of sin by committing it, though whoever has heard and knows is included in the curse. We hold that it is likewise with all these enormities, except those which are necessarily known as being of the religion (def: fl.3(N:)).
