Anas told that one morning he took ‘Abdallah b. Abu Talha to God’s messenger for him to chew something and rub his palate with it,* and found him with a branding-iron in his hand branding the camels of the sadaqa. *This was a custom for the purpose of acquiring a blessing for children. (Bukhari and Muslim.)
