Safiyya bint Abu 'Ubaid reported on the authority of Hafsa or 'A'isha (Allah be pleased with thein) or from both of them that Allah's Messenger (may peace he upon him) said: It is not permissible for a woman believing in Allah and the Hereafter (or believing in Allah and His Messenger) that she should observe mourning for the dead beyond three days except in case of her husband.

A hadith like this is transmitted on the authority of Nafi'.

Safiyya bint Abu 'Ubaid reported that she heard Hafsa daughter of Umar (RA) , (and) wife of Allah's Prophet ( صلی اللہ علیہ وسلم ) , narrating a hadith like this from Allah's Apostle ( صلی اللہ علیہ وسلم ) , and she made this addition: "She should abstain from adorning herself (in case of the death of her husband) for four months and ten days."

Safiyya bint Abu 'Ubaid narrated this tradition of Allah's Prophet ( صلی اللہ علیہ وسلم ) on the authority of some wives of Allah's Apostle ( صلی اللہ علیہ وسلم )
