(50) بَابُ قُبْلَةِ الصِّبْيَانِ
Abu Hurayra said, "The Messenger of Allah, may Allah bless him and grant
him peace, kissed Hasan ibn 'Ali while al-Aqra' ibn Habis at-Tamimi was sitting
with him. Al-Aqra' observed, 'I have ten children and I have never kissed any of
them.' The Messenger of Allah, may Allah bless him and grant him peace, looked
at him and said, 'Whoever does not show mercy will not be shown mercy.'"
