Fiqh-us-Sunnah Volume 5, Hajj and ‘Umrah, Fiqh 5.046D.
Asma bint Abi Baker reported: “We went for Hajj with the Prophet (peace be upon him). When we reached a place called ‘Arj the Prophet (peace be upon him) stopped, and so did we. ‘Aishah sat by the Prophet (peace be upon him), and I sat next to Abu Bakr. Their travel supplies were with a servant of Abu Bakr. He sat down waiting for his servant. When the servant came he was walking on foot, and had no camel with him. Abu Bakr asked him about his camel. The servant replied: ‘I lost it yesterday.’ At this Abu Bakr got angry and said to him: ‘You had only one camel (to look after) and you lost it.’ And he beat him. The Prophet (peace be upon him) smiled and said: ‘Look at this muhrim–Abu Bakr! What is he doing?’ And he kept on smiling and repeating this.” (Reported by Ahmad, Abu Daw’ud, and Ibn Majah)
