What was the special action taken by Prophet Muhammad (saw) when Zainab bint Humaid brought her son 'Abdullah bin Hisham to him?
 Narrated `Abdullah bin Hisham:                     who was born during the lifetime of the Prophet that his mother, Zainab bint Humaid had taken him to Allah's Apostle and said, "O Allah's Apostle! Take his Pledge of allegiance (for Islam)." The Prophet said, "He (`Abdullah bin Hisham) is a little child," and passed his hand over his head and invoked Allah for him. `Abdullah bin Hisham used to slaughter one sheep as a sacrifice on behalf of all of his family.
