* Narrated Abu Burda:Sahih Bukhari 2.376 talks about Jews, while Sahih Bukhari 2.375 has A'isha contradicting 'Umar, saying that it applies only to nonbelievers.
That his father said, "When Umar was stabbed, Suhaib started crying: O my brother! 'Umar said, 'Don't you know that the Prophet said: The deceased is tortured for the weeping of the living'?" (Sahih Bukhari 2.377, Sahih Bukhari 2.378, Sahih Bukhari 2.378, Sahih Bukhari 2.380)
* Narrated 'Aisha:However, the next hadith allows a limited time of mourning.
When the Prophet got the news of the death of Ibn Haritha, Ja'far and Ibn Rawaha he sat down and looked sad and I was looking at him through the chink of the door. A man came and told him about the crying of the women of Ja'far. The Prophet ordered him to forbid them. The man went and came back saying that he had told them but they did not listen to him. The Prophet said, "Forbid them." So again he went and came back for the third time and said, "O Allah's Apostle! By Allah, they did not listen to us at all." ('Aisha added): Allah's Apostle ordered him to go and put dust in their mouths. I said, (to that man) "May Allah stick your nose in the dust (ie. humiliate you)! You could neither (persuade the women to) fulfill the order of Allah's Apostle nor did you relieve Allah's Apostle from fatigue. " (Sahih Bukhari 2.386)
* Narrated Um-'Atiya:see hadith above for Muhammad's forbidding of mourning.
We were forbidden to mourn for a dead person for more than three days except in the case of a husband for whom mourning was allowed for four months and ten days. (During that time) we were not allowed to put ko,hl (Antimony eye power) in our eyes or to use perfumes or to put on colored clothes except a dress made of 'Asb (a kind of Yemen cloth, very coarse and rough). We were allowed very light perfumes at the time of taking a bath after menses and also we were forbidden to go with the funeral procession. (Sahih Bukhari 1.310, Sahih Bukhari 2.369, Sahih Bukhari 2.370, Sahih Bukhari 2.371)
