Hadith 2118
Ibn Abbas (RA) reported that Allah's Messenger (ﷺ) saw an ass which had been cauterised on the face. He disapproved of it saying: By Allah, I do not cauterise (the animal) but on a part at a distance from the face, and commanded (for the cauterisation) of his ass and it was cauterised on the buttocks and he was the first to cauterise on the buttocks.
Hadith 2549
Yazid bin Abu Habib reported that Na'im, the freed slave of Umm Salamah, reported to him that 'Abdullah bin 'Amr bin 'As said: There came to Allah's Apostle (ﷺ) a person and said: I owe allegiance to you for migration and Jihad seeking reward only from Allah. He (the Holy Prophet) said: Is one from amongst your parents living? He said: Yes, of course, both are living. He further asked: Do you want to seek reward from Allah? He said: Yes. Thereupon Allah's Messenger (ﷺ) said: Go back to your parents and accord them benevolent treatment.
