Sahih al-Bukhari Book 78, Hadith 27
The Prophet (ﷺ) came out towards us, while carrying Umamah, the daughter of Abi Al-As (his granddaughter)
over his shoulder. He prayed, and when he wanted to bow, he put her down, and when he
stood up, he lifted her up.
(the wife of the Prophet) A lady along with her two daughters came to me asking me (for some alms), but she found nothing with me except one date which I gave to her and she divided it between her two daughters, and then she got up and went away. Then the Prophet (ﷺ) came in and I informed him about this story. He said, "Whoever is in charge of (put to test by) these daughters and treats them generously, then they will act as a shield for him from the (Hell) Fire."
Allah's Messenger (ﷺ) kissed Al-Hasan bin `Ali while Al-Aqra' bin H`Abis at-Tamim was sitting beside him. Al-Aqra said, "I have ten children and I have never kissed anyone of them," Allah's Messenger (ﷺ) cast a look at him and said, "Whoever is not merciful to others will not be treated mercifully."
