Abdullah bin Ja'far reported that when Allah's Messenger (may peace be, upon him) came back from a journey, the children of his family used to accord him welcome. It was in this way that once he came back from a journey and I went to him first of all. He mounted me before him. Then there came one of the two sons of Fatima and he mounted him behind him and this is how we three entered Madinah riding on a beast.

Abdullah bin Jafar said “When the Prophet ﷺ arrived after a journey, we were taken for his reception. Any of us who met him first he lifted him in front of him. As I was the first to meet him, he lifted me in front of him. Then Hasan or Hussain was brought to him and he set him behind him. We the entered Madeenah and we (were) riding so (three on one beast). ”

´Abdullah bin Ja'far said:` "Whenever the Messenger of Allah(ﷺ) came back from a journey, he would be met by us(children). (One day) he was met by me and Hasan or Husain. He made one of us ride in front of him and the other behind him, until we came to Al-Madinah."

Benefits and Issues:
➊ Elders should treat children with kindness.
➋ It is permissible to welcome someone returning from a journey, but one should not display unnecessary formalities in doing so.
➌ More than one person may ride an animal, provided that the animal can easily bear the load. On a long journey or if the animal is weak, it is not appropriate for two people to ride together.
➍ Abdullah bin Ja‘far (radi Allahu anhu) and Hasan or Husayn (radi Allahu anhuma) were children. The combined weight of both of them was not equal to that of one adult, so three people riding together did not cause hardship for the animal.
