Chapter: Whoever sat down and looked sad when afflicted with a calamity
Narrated `Aisha:
When the Prophet (ﷺ) 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 (ﷺ) 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 (p.b.u.h) said, "Forbid them." So again he went and came back for the third time and said, "O Allah's Messenger (ﷺ)! By Allah, they did not listen to us at all." (`Aisha added): Allah's Messenger (ﷺ) ordered him to go and put dust in their mouths. I said, (to that man) "May Allah stick your nose in the dust (i.e. humiliate you)! You could neither (persuade the women to) fulfill the order of Allah's Messenger (ﷺ) nor did you relieve Allah's Messenger (ﷺ) from fatigue. " - Sahih:Al Bukhari:1299 (islam)

-Is it because of the Punishment of the Grave?

Chapter: The Rulings Of Mourning For Woman Whose Husband Has Died
Humaid ibn Nafi' reported the following three traditions on the authority of Zaynab, daughter of Abu Salamah:
Zainab said: I visited Umm Habibah when her father AbuSufyan, died. She asked for some yellow perfume containing saffron (khaluq) or something else. Then she applied it to a girl and touched her cheeks. She said: I have no need of perfume, but I heard the Messenger of Allah (ﷺ) say: It is not lawful for a woman who believes in Allah and the Last Day to observe mourning for one who has died, more than three nights, except for four months and ten days in the case of a husband. Zaynab said: I also visited Zaynab, daughter of Jahsh, when her brother died. She asked for some perfume and used it upon herself. She then said: I have no need of perfume, but I heard the Messenger of Allah (ﷺ) say when he was on the pulpit: It is not lawful for a woman who believes in Allah and the Last Day to observe mourning for one who has died, more than three nights, except for four months and ten days in the case of a husband. Zaynab said: I heard my mother, Umm Salamah, say: A woman came to the Messenger of Allah (ﷺ) and said: Messenger of Allah, the husband of my daughter has died, and she is suffering from sore eyes; may we put antimony in her eyes? The Messenger of Allah (ﷺ) said: No. He said this twice or thrice. Each time he said: No. The Messenger of Allah (ﷺ) said: The waiting period is now four months and ten days. In pre-Islamic days one of you used to throw away a piece of dung at the end of a year. Humayd said: I asked Zaynab: What do you mean by throwing away a piece of dung at the end of a year. Zaynab replied: When the husband of a woman died, she entered a small cell and put on shabby clothes, not touching perfume or any other thing until a year passed. Then an animal such as donkey or sheep or bird was provided for her. She rubbed herself with it. The animal with which she rubbed herself rarely survived. She then came out and was given a piece of dung which she threw away. She then used perfume or something else which she desired. Abu Dawud said: The Arabic word "hafsh" means a small cell. - Sahih:Abu Dawud:2299 (islam)
