(63) باب تَرْكِ الزِّينَةِ لِلْحَادَّةِ الْمُسْلِمَةِ دُونَ الْيَهُودِيَّةِ وَالنَّصْرَانِيَّةِ
Zainab said:
"Then I went into Zainab bint Jahsh when her brother died, and she called for some perfume and put some on. Then she said: 'By Allah, I do not have any need for perfume but I heard the Messenger of Allah say on the Minbar: It is not permissible for any woman who believes in Allah and the Last Day to mourn for anyone who dies for more than three days, except for a husband, (for whom the mourning period is) four months and ten days.'"
