The Messenger of Allah ﷺ had him ride behind him on his mount. When he had settled upon it, the Messenger of Allah ﷺ said "Allahu Akbar" three times, praised Allah three times, glorified Allah three times, and declared Allah's oneness once. Then he leaned back and laughed. He turned to Ali and said, "There is no man who mounts his beast and does as I have done except that Allah turns toward him and laughs at him as I have laughed at you."
حدثنا أبو المغيرة حدثنا أبو بكر بن عبد الله عن علي بن أبي طلحة
أن رسول الله ﷺ أردفه على دابته فلما استوى عليها كبر رسول الله ﷺ ثلاثا وحمد الله ثلاثا وسبح الله ثلاثا وهلل الله واحدة ثم استلقى عليه فضحك ثم أقبل علي فقال ما من امرئ يركب دابته فيصنع كما صنعت إلا أقبل الله تبارك وتعالى فضحك إليه كما ضحكت إليك

Its isnad is daif. Abu Bakr bin Abdullah is Abu Bakr bin Abdullah bin Abu Maryam, whose weakness we have already explained at 113 and 1464.Ali bin Abu Talha is trustworthy, though some have criticized him. It appears they criticized him because of his Shia leanings, and Muslim included him in his narrations, but he did not hear from Ibn Abbas.The hadith is found in Majma al-Zawaid 10:131, where it is attributed solely to the Musnad, and its flaw is attributed to Abu Bakr bin Abu Maryam.
