Muhammad bin Abd al-Rahman (may Allah have mercy on him) said: "The Prophet (peace and blessings be upon him) had that woman crucified after she had been killed."
Al-Waqidi (may Allah have mercy on him) said: It is established with us that she was killed and that the goat's meat was burned.
The Shaykh (may Allah have mercy on him) said: The narrations differ about her being killed. The most authentic of them is the narration of Sayyiduna Anas bin Malik (may Allah be pleased with him), which mentions that she was given no punishment. But we will interpret it as meaning that as long as nothing had happened, he (peace and blessings be upon him) did not punish that woman, and when Sayyiduna Bishr bin al-Bara (may Allah be pleased with him) died, she too was killed; and each narrator reported what he himself witnessed. And Allah knows best.
