Mujahid said that «وبال أمرها‏» i.e. «جزاء أمرها» means he will have to bear the burden of his sin, which is in the form of punishment; that is what is meant.

Narrated Salim: That `Abdullah bin `Umar told him that he had divorced his wife while she was in her menses so `Umar informed Allah's Messenger of that. Allah's Messenger became very angry at that and said, "(Ibn `Umar must return her to his house and keep her as his wife till she becomes clean and then menstruates and becomes clean again, whereupon, if he wishes to divorce her, he may do so while she is still clean and before having any sexual relations with her, for that is the legally prescribed period for divorce as Allah has ordered."

And by «أولات الأحمال» is meant «ذات حمل» , which means a pregnant woman.

Narrated Abu Salama: A man came to Ibn `Abbas while Abu Huraira was sitting with him and said, "Give me your verdict regarding a lady who delivered a baby forty days after the death of her husband." Ibn `Abbas said, "Her waiting period is the later (i.e. the longer) of the two prescribed periods." I said "For those who are pregnant, their prescribed period is until they deliver their burdens." Abu Huraira said, I agree with my nephew (Abu Salama)." Then Ibn `Abbas sent his slave, Kuraib to Um Salama to ask her (regarding this matter). She replied. "The husband of Subai'a al Aslamiya was killed while she was pregnant, and she delivered a baby forty days after his death. Then her hand was asked in marriage and Allah's Messenger married her (to somebody). Abu As-Sanabil was one of those who asked for her hand in marriage".

And Sulaiman bin Harb and Al-Nu’man narrated that Hammad bin Zaid narrated to us, from Ayyub, and from him Muhammad bin Sirin narrated that:
I was present in a gathering in which Abdur Rahman bin Abi Laila was also present. His students used to respect him greatly. They mentioned (the matter) to him, and he stated the later of the two terms. There, I narrated the statement of Sabi’ah bint Al-Harith from Abdullah bin Utbah bin Mas’ud, upon which one of his students warned me by biting his lip and making gestures with his tongue and eyes. Muhammad bin Sirin narrated that I understood and said that Abdullah bin Utbah is still alive in Kufa. If I attribute a lie to him, it would be a great boldness. The person who warned me became embarrassed at this, and Abdur Rahman bin Abi Laila said,“But his uncle did not say this.”(Ibn Sirin narrated that) Then I met Abu Atiyyah Malik bin Amir and asked him about this issue. He also began to narrate the hadith of Sabi’ah, but I asked him,“Have you also heard anything about this from Abdullah bin Mas’ud (may Allah be pleased with him)?”He narrated that we were present in the service of Abdullah bin Mas’ud (may Allah be pleased with him), so he said,“Do you want to be harsh on her (whose husband has died and she is pregnant, by prolonging the period of waiting) and are not ready to grant ease and concession? The fact is that the small Surah An-Nisa (i.e., Surah At-Talaq) was revealed after the big Surah An-Nisa, and he said «وأولات الأحمال أجلهن أن يضعن حملهن‏» the verse, and the waiting period for pregnant women is until they deliver their pregnancy.”

Narrated Ibn `Abbas: If someone says to his wife, "You are unlawful to me." he must make an expiation (for his oath). Ibn `Abbas added: There is for you in Allah's Messenger , an excellent example to follow.

Narrated `Aisha: Allah's Messenger used to drink honey in the house of Zainab, the daughter of Jahsh, and would stay there with her. So Hafsa and I agreed secretly that, if he come to either of us, she would say to him. "It seems you have eaten Maghafir (a kind of bad-smelling resin), for I smell in you the smell of Maghafir," (We did so) and he replied. "No, but I was drinking honey in the house of Zainab, the daughter of Jahsh, and I shall never take it again. I have taken an oath as to that, and you should not tell anybody about it."

Narrated Ibn `Abbas: For the whole year I had the desire to ask `Umar bin Al-Khattab regarding the explanation of a Verse (in Surat Al-Tahrim) but I could not ask him because I respected him very much. When he went to perform the Hajj, I too went along with him. On our return, while we were still on the way home. `Umar went aside to answer the call of nature by the Arak trees. I waited till he finished and then I proceeded with him and asked him. "O chief of the Believers! Who were the two wives of the Prophet who aided one another against him?" He said, "They were Hafsa and `Aisha." Then I said to him, "By Allah, I wanted to ask you about this a year ago, but I could not do so owing to my respect for you." `Umar said, "Do not refrain from asking me. If you think that I have knowledge (about a certain matter), ask me; and if I know (something about it), I will tell you." Then `Umar added, "By Allah, in the Pre-lslamic Period of Ignorance we did not pay attention to women until Allah revealed regarding them what He revealed regarding them and assigned for them what He has assigned. Once while I was thinking over a certain matter, my wife said, "I recommend that you do so-and-so." I said to her, "What have you got to do with the is matter? Why do you poke your nose in a matter which I want to see fulfilled.?" She said, How strange you are, O son of Al-Khattab! You don't want to be argued with whereas your daughter, Hafsa surely, argues with Allah's Messenger so much that he remains angry for a full day!" `Umar then reported; how he at once put on his outer garment and went to Hafsa and said to her, "O my daughter! Do you argue with Allah's Messenger so that he remains angry the whole day?" H. afsa said, "By Allah, we argue with him." `Umar said, "Know that I warn you of Allah's punishment and the anger of Allah's Messenger . . . O my daughter! Don't be betrayed by the one who is proud of her beauty because of the love of Allah's Messenger for her (i.e. `Aisha)." `Umar addled, "Then I went out to Um Salama's house who was one of my relatives, and I talked to her. She said, O son of Al-Khattab! It is rather astonishing that you interfere in everything; you even want to interfere between Allah's Apostle and his wives!' By Allah, by her talk she influenced me so much that I lost some of my anger. I left her (and went home). At that time I had a friend from the Ansar who used to bring news (from the Prophet) in case of my absence, and I used to bring him the news if he was absent. In those days we were afraid of one of the kings of Ghassan tribe. We heard that he intended to move and attack us, so fear filled our hearts because of that. (One day) my Ansari friend unexpectedly knocked at my door, and said, "Open Open!' I said, 'Has the king of Ghassan come?' He said, 'No, but something worse; Allah's Messenger has isolated himself from his wives.' I said, 'Let the nose of `Aisha and Hafsa be stuck to dust (i.e. humiliated)!' Then I put on my clothes and went to Allah's Messenger 's residence, and behold, he was staying in an upper room of his to which he ascended by a ladder, and a black slave of Allah's Messenger was (sitting) on the first step. I said to him, 'Say (to the Prophet) `Umar bin Al-Khattab is here.' Then the Prophet admitted me and I narrated the story to Allah's Messenger . When I reached the story of Um Salama, Allah's Messenger smiled while he was lying on a mat made of palm tree leaves with nothing between him and the mat. Underneath his head there was a leather pillow stuffed with palm fibres, and leaves of a saut tree were piled at his feet, and above his head hung a few water skins. On seeing the marks of the mat imprinted on his side, I wept. He said.' 'Why are you weeping?' I replied, "O Allah's Messenger! Caesar and Khosrau are leading the life (i.e. Luxurious life) while you, Allah's Messenger though you are, is living in destitute". The Prophet then replied. 'Won't you be satisfied that they enjoy this world and we the Hereafter?' "

In this chapter, there is also a hadith of Aisha (may Allah be pleased with her) narrated from the Prophet (peace and blessings of Allah be upon him).
