وعن ابن عباس رضي الله عنهما قال‏:‏ قال رسول الله صلى الله عليه وسلم لأشج عبد القيس‏:‏ “إن فيك خصلتين يحبهما الله‏:‏ الحلم والأناة”‏.‏ ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏

Abu Ya'la Shaddad bin 'Aus (May Allah be pleased with him) reported

Messenger of Allah (ﷺ) said, "Verily Allah has prescribed Ihsan (kindness) for everything. So when you kill, you must make the killing in the best manner; when you slaughter, make your slaughter in the best manner. Let one of you sharpen his knife and give ease to his animal (in order to reduce his pain)."[Muslim].
