Anas bin Malik reported,

I brought Abdullah bin Abu Talha al-Ansari to the Messenger of Allah ﷺ when he was born. The Messenger of Allah ﷺ was wrapped in a cloak, treating one of his camels with tar.He asked, "Do you have any dates with you?"I said, "Yes," and handed him some dates. He put them in his mouth and chewed them, then opened the baby's mouth and placed the chewed dates inside. The baby began to lick and taste them.The Messenger of Allah ﷺ said, "The Ansar love dates," and he named him Abdullah.

عن أنس قال

ذهبت بعبد الله بن أبي طلحة الأنصاري إلى رسول الله ﷺ حين ولد، ورسول الله ﷺ في عباءة يهنأ بعيرا له. فقال: هل معك تمر؟ فقلت: نعم، فناولته تمرات. فألقاهن في فيه فلاكهن، ثم فغر فا الصبي فمجه في فيه، فجعل الصبي يتلمظه. فقال رسول الله ﷺ: حب الأنصار التمر وسماه: عبد الله.
