"....Then he said, 'Where is the little one? Call the little one to me.' Hasan came running and jumped into his lap. Then he put his hand in his beard. Then the Prophet, may Allah bless him and grant him peace, opened his mouth and put his mouth in his mouth. Then he said, O Allah, I love him, so love him and the one who loves him!'" (Al-Adab Al-Mufrad 1183, grade: Hasan)
