مُسْنَدُ أَحْمَدَ
Musnad Ahmad 4028
Musnad of Abdullah bin Mas'ood
It was narrated that ‘Abdullah said: We came to the Messenger of Allah (ﷺ) concerning a man, asking for permission to cauterise him, but he remained silent. We asked him again and he remained silent. Then we asked him a third time and he said: “Cauterise him using hot stones as if you wish," as if he was angry.
