Ayesha reported,

Aisha said, "I went out with the Prophet ﷺ on one of his journeys when I was a young Jariya, slender and not yet filled out. He said to the people, 'Go on ahead,' so they went on ahead. Then he said to me, 'Come, let me race you.' So I raced him and beat him. He said nothing about it.Later, after I had gained weight and grown heavier and had forgotten the earlier incident, I went out with him on another journey. He said to the people, 'Go on ahead,' so they went on ahead. Then he said, 'Come, let me race you.' So I raced him, and this time he beat me. He began to laugh and said, 'This one for that one.'"

عن عائشة قالت

خرجت مع النبي ﷺ في بعض أسفاره وأنا جارية لم أحمل اللحم، ولم أبدن، فقال للناس: تقدموا فتقدموا. ثم قال لي: تعالى حتى أسابقك فسابقته فسبقته، فسكت عني حتى إذا حملت اللحم، وبدنت، ونسيت خرجت معه في بعض أسفاره، فقال للناس: تقدموا فتقدموا ثم قال: تعالى حتى أسابقك فسابقته فسبقني، فجعل يضحك وهو يقول: هذه بتلك.
