Abdullah bin 'Awn bin Artaban عبد الله بن عون بن أرطبان الخزار · The Book of Divorce

"Ibn 'Abbas, Abu Hurairah and I were together, and Ibn 'Abbas said: 'If a woman gives birth after her husband dies, her 'Iddah is the longer of the two periods.'" Abu Salamah said: "We sent Kuraib to Umm Salamah to ask her about that. He came to us and told us from her that the husband of Subai'ah died and she gave birth a few days after her husband died, and the Messenger of Allah told her to get married."
