Hadith 35

“The Messenger of Allah (ﷺ) kissed Hasan ibn 'Ali while al-Aqra' ibn Habis at-Tamimi (رضي الله عنه) was sitting with him. Al-Aqra' observed, 'I have ten children and I have never kissed any of them.' The Messenger of Allah (ﷺ) looked at him and said, 'Whoever does not show mercy will not be shown mercy.'”
