It was narrated from 'Ubaidullah bin 'Abdullah that 'Abdullah bin 'Utbah wrote to 'Umar bin 'Abdullah bin Al-Arqam Az-Zuhri, telling him:
Go to Subai'ah bint Al-Harith Al-Aslamiyyah, and ask her about the ruling of the Messenger of Allah concerning her pregnancy. He said: So 'Umar bin 'Abdullah went to her and asked her. She told him that she was married to Sa'd bin Khawlah, who was one of the Companions of the Messenger of Allah who had been present at Badr. He died during the Farewell Pilgrimage, and she gave birth before four months and ten days had passed since her husband's death. When her Nifas ended, Abu As-Sanabil -a man from Banu 'Abd Ad-Dar- went to her and saw that she had adorned herself. He said: 'Perhaps you want to get married before four months and ten days has passed?' She said: 'When I heard that from Abu As-Sanabil, I went to the Messenger of Allah and told him my story. The Messenger of Allah said: 'It is permissible for you to marry when you gave birth.''
