Once the Prophet (ﷺ) went out during the day. Neither did he talk to me nor I to him till he reached the market of Banî Qainuqâ ', and then he sat in the compound of Fâțima's house and asked about the small boy (his grandson Al-Hasan 1) but kept the boy in for a while. I thought she was either changing his clothes or giving the boy a bath. After a while the boy came out running and the Prophet (ﷺ) embraced and kissed him and then said, "O Allah ! Love him, and love whoever loves him." [3:333-O.B]
