Anas (May Allah be pleased with him) reported: One of the sons of Abu Talhah (May Allah be pleased with him) was ailing. Abu Talhah went out and the boy died in his absence. When he came back, he inquired, "How is the boy?". Umm Sulaim, the mother of the boy, replied, "Better than before". Then she placed his evening meal before him and he ate it; and thereafter slept with her. At last, she said to him: "Arrange for the burial of the boy". In the morning, Abu Talhah went to Messenger of Allah (ﷺ) and informed him of the event. He enquired, "Did you sleep together last night?" Abu Talhah replied in the affirmative, on which the Prophet (ﷺ) supplicated, "O Allah bless them." Thereafter, she gave birth to a boy. Abu Talhah said to me: "Take up the boy and carry him to the Prophet (ﷺ)"; and he sent some dates with him. The Prophet (ﷺ) enquired, "Is there anything with him?" He said; "Yes, some dates". The Prophet (ﷺ) took a date, chewed it and put it in the mouth of the baby and rubbed the chewed date around the baby's gum and named him 'Abdullah..
