Abdullah b. Ja'a'far reported that when Messenger of Allah ﷺ came back from a journey he met us. Once he met me, Hasan or Husain, and he mounted one of us before him and the other one behind him until we entered Medina.
كَانَ النَّبِيُّ ﷺ إِذَا قَدِمَ مِنْ سَفَرٍ تُلُقِّيَ بِنَا قَالَ فَتُلُقِّيَ بِي وَبِالْحَسَنِ أَوْ بِالْحُسَيْنِ قَالَ فَحَمَلَ أَحَدَنَا بَيْنَ يَدَيْهِ وَالآخَرَ خَلْفَهُ حَتَّى دَخَلْنَا الْمَدِينَةَ
"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."
كَانَ رَسُولُ اللَّهِ ﷺ إِذَا قَدِمَ مِنْ سَفَرٍ تُلُقِّيَ بِنَا قَالَ فَتُلُقِّيَ بِي وَبِالْحَسَنِ أَوْ بِالْحُسَيْنِ قَالَ فَحَمَلَ أَحَدَنَا بَيْنَ يَدَيْهِ وَالآخَرَ خَلْفَهُ حَتَّى قَدِمْنَا الْمَدِينَةَ
[Machine] The translation is: The Messenger of Allah ﷺ used to carry me and Al-Hasan or Al-Husain (his grandsons) on his shoulders, and he would say, "And I see him (the Prophet) saying, 'Al-Hasan, carry me between his hands and Al-Husain behind him until we reach Madinah while riding on the animal that the Prophet ﷺ used to ride on."
كَانَ رَسُولُ اللَّهِ ﷺ إِذَا قَفَلَ تُلُقِّيَ بِي وَبِالْحَسَنِ أَوْ بِالْحُسَيْنِ قَالَ وَأُرَاهُ قَالَ الْحَسَنَ فَحَمَلَنِي بَيْنَ يَدَيْهِ وَالْحَسَنَ وَرَاءَهُ حَتَّى قَدِمْنَا الْمَدِينَةَ وَنَحْنُ عَلَى الدَّابَّةِ الَّتِي عَلَيْهَا النَّبِيُّ ﷺ
