It is narrated from Hazrat Anas (may Allah be pleased with him) that when a son, Abdullah, was born in the house of Hazrat Abu Talha (may Allah be pleased with him), I took the child and presented him to the service of the Prophet (peace and blessings be upon him). I saw that the Prophet (peace and blessings be upon him) was applying tar to his camels. The Prophet (peace and blessings be upon him) asked, "Do you have any dates?" I replied, "Yes!" The Prophet (peace and blessings be upon him) took a date, chewed it in his mouth to soften it, gathered his saliva, and put it into the child's mouth, which he began to suck. The Prophet (peace and blessings be upon him) said, "Dates are a beloved thing of the Ansar," and the Prophet (peace and blessings be upon him) named him Abdullah.
