Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: Once Sayyiduna Abbas (may Allah be pleased with him) branded the face of his camel or some animal. When the Prophet Muhammad (peace and blessings be upon him) saw this, he became angry. Sayyiduna Abbas (may Allah be pleased with him) said: From now on, I will always brand on the back part of its body. Then Sayyiduna Abbas (may Allah be pleased with him) branded it on its ja'irah (the part of the thigh where the animal's tail reaches when it wags).
