Some hadiths on beating women and slaves

Sahih Bukhari 8.68:
Narrated `Abdullah bin Zam`a: The Prophet forbade laughing at a person who passes wind, and said, "How does anyone of you beat his wife as he beats the stallion camel and then he may embrace (sleep with) her?" And Hisham said, "As he beats his slave"

Sahih Muslim Bk 4, Number 2127: Muhammad b. Qais said (to the people): Should I not narrate to you (a hadith of the Holy Prophet) on my authority and on the authority of my mother? We thought that he meant the mother who had given him birth. He (Muhammad b. Qais) then reported that it was 'A'isha who had narrated this: Should I not narrate to you about myself and about the Messenger of Allah (may peace be upon him)? We said: Yes. She said: When it was my turn for Allah's Messenger (may peace be upon him) to spend the night with me, he turned his side, put on his mantle and took off his shoes and placed them near his feet, and spread the corner of his shawl on his bed and then lay down till he thought that I had gone to sleep. He took hold of his mantle slowly and put on the shoes slowly, and opened the door and went out and then closed it lightly. I covered my head, put on my veil and tightened my waist wrapper, and then went out following his steps till he reached Baqi'. He stood there and he stood for a long time. He then lifted his hands three times, and then returned and I also returned. He hastened his steps and I also hastened my steps. He ran and I too ran. He came (to the house) and I also came (to the house). I, however, preceded him and I entered (the house), and as I lay down in the bed, he (the Holy Prophet) entered the (house), and said: Why is it, O 'A'isha, that you are out of breath? I said: There is nothing. He said: Tell me or the Subtle and the Aware would inform me. I said: Messenger of Allah, may my father and mother be ransom for you, and then I told him (the whole story). He said: Was it the darkness (of your shadow) that I saw in front of me? I said: Yes. He struck me on the chest which caused me pain, and then said: Did you think that Allah and His Apostle would deal unjustly with you? She said: Whatsoever the people conceal, Allah will know it. He said: Gabriel came to me when you saw me. He called me and he concealed it from you. I responded to his call, but I too concealed it from you (for he did not come to you), as you were not fully dressed. I thought that you had gone to sleep, and I did not like to awaken you, fearing that you may be frightened. He (Gabriel) said: Your Lord has commanded you to go to the inhabitants of Baqi' (to those lying in the graves) and beg pardon for them. I said: Messenger of Allah, how should I pray for them (How should I beg forgiveness for them)? He said: Say, Peace be upon the inhabitants of this city (graveyard) from among the Believers and the Muslims, and may Allah have mercy on those who have gone ahead of us, and those who come later on, and we shall, God willing, join you.

Sahih Bukhari 8.827: Narrated `Aisha: Abu Bakr came to me while Allah's Apostle was sleeping with his head on my thigh. Abu Bakr said (to me), "You have detained Allah's Apostle and the people, and there is no water in this place." So he admonished me and struck my flanks with his hand, and nothing could stop me from moving except the reclining of Allah's Apostle (on my thigh), and then Allah revealed the Divine Verse of Tayammum.
8.828: Narrated Aisha: Abu Bakr came to towards me and struck me violently with his fist and said, "You have detained the people because of your necklace." But I remained motionless as if I was dead lest I should awake Allah's Apostle although that hit was very painful.
