[Machine] That they (widows) should wait [for] their waiting period. But if you fear that they will not be able to maintain [the limits of] Allah, then there is no blame upon them for what he ransoms her thereby. These are the limits of Allah, so do not transgress them. And whoever transgresses the limits of Allah, it is those who are the wrongdoers.

And those who are taken in death among you and leave wives behind - they, [the wives, shall] wait four months and ten [days].

[Machine] "Whomsoever he wills to curse, I shall curse him as well. The term of the pregnant women will not be fulfilled [i.e., they will not give birth] except after [the passing of] a sign from the deceased [husband]. And those among you who pass away and leave behind wives, the wives will wait for [the completion of] four months and ten [days]."

"Whoever wants, I will meet and debate with him and invoke the curse of Allah upon those who lie. The Verse: 'And for those who are pregnant (whether they are divorced or their husbands are dead), their 'Iddah (prescribed period) is until they lay down their burden.' was only revealed after the Verse about women whose husbands die. 'When a woman whose husband has died gives birth, it becomes permissible for her to marry.'" This is the wording of Maimun (one of the narrators). (Using translation from Nasāʾī 3522)
