'Aishah (May Allah bepleased with her) reported:
Some bedouins came to Messenger of Allah (ﷺ) and asked: "Do you kiss your children?" He said, "Yes". They then said: "By Allah, we do not kiss them." The Prophet (ﷺ) replied, "I cannot help you if Allah has snatched kindness from your hearts".[Al-Bukhari and Muslim].
