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.[Al-Bukhari and Muslim].The narration in Bukhari adds: Ibn 'Uyainah relates that a man from the Ansar told him that he had seen nine sons of this 'Abdullah, every one of whom had committed the Noble Qur'an to memory.The narration of Muslim says: The son of Abu Talhah (May Allah be pleased with him) who was born of Umm Sulaim died. She (Umm Sulaim) said to the members of the family: "Do not tell Abu Talhah about his son until I mention it to him myself." Abu Talhah came (home) and she gave him supper. He ate and drank. She then beautified herself the best way she ever did and he slept with her. When she saw that he was satisfied after sexual intercourse with her, she said, "O Abu Talhah! If some people borrow something from another family and then (the members of the family) ask for its return, would they refuse to give it back to them." He said, "No". She said, "Then hope reward for your son". Abu Talhah got angry, and said; "You left me uninformed until I stained myself (with sexual intercourse) and then you told me about my son. "He went to Messenger of Allah (ﷺ) and informed him about the matter. Thereupon Messenger of Allah (ﷺ) said, "May Allah bless the night you spent together!" He (the narrator) said: She conceived. (One day) Messenger of Allah (ﷺ) was in the course of a journey and she was along with him. When Messenger of Allah (ﷺ) used to come back to Al-Madinah from a journey, he would not enter it (during the night). When the people came near Al- Madinah, she felt labour pains. He (Abu Talhah) remained with her and Messenger of Allah (ﷺ) proceeded on. Abu Talhah said: "O Rubb, You know that I love to go along with Messenger of Allah (ﷺ) when he goes out and enter along with him when he enters, and I have been detained as You see." Umm Sulaim then said: "O Abu Talhah, I do not feel (so much pain) as I was feeling earlier, so we better proceed on. So we proceeded on and she felt the labour of delivery as they reached (Al-Madinah). She gave birth to a male child. My mother said to me: "O Anas, none should suckle him until you go to Messenger of Allah (ﷺ) tomorrow morning." The next morning I carried the baby with me to Messenger of Allah (ﷺ), and narrated the rest of the story.[Al-Bukhari and Muslim].
