Abu Dawud Book 4, Hadith Number 1814.

Narated By Asma’ bint AbuBakr : We came out for performing hajj along with the Apostle of Allah (PBUH). When we reached al-Araj, the Apostle of Allah (PBUH) alighted and we also alighted. ‘Aisha sat beside the Apostle of Allah (PBUH) and I sat beside my father (AbuBakr). The equipment and personal effects of AbuBakr and of the Apostle of Allah (PBUH) were placed with AbuBakr’s slave on a camel. AbuBakr was sitting and waiting for his arrival. He arrived but he had no camel with him. He asked:

Where is your camel? He replied: I lost it last night. AbuBakr said: There was only one camel, even that you have lost. He then began to beat him while the Apostle of Allah (PBUH) was smiling and saying: Look at this man who is in the sacred state (putting on ihram), what is he doing?

Ibn AbuRizmah said: The Apostle of Allah (PBUH) spoke nothing except the words: Look at this man who is in the sacred state (wearing ihram), what is he doing? He was smiling (when he uttered these words).
