Hazrat Abdullah (may Allah be pleased with him) says that if someone wishes, I can swear an oath and say that the small Surah an-Nisa (Surah at-Talaq) (in which the waiting period for childbirth is mentioned) was revealed after the verse { أَرْبَعَۃ أَشْھُر وَّعَشْرًا } of the Holy Qur'an.

Hazrat Abu Qalabah (may Allah have mercy on him) says that if a pregnant woman's husband passes away, her waiting period (iddah) will be completed as soon as she gives birth to the child.

Hasan (may Allah have mercy on him) says that if a person divorces a pregnant woman or her husband passes away, then her waiting period (‘iddah) is until she gives birth.

Hazrat Abdullah (may Allah be pleased with him) says that the waiting period (‘iddah) of a pregnant woman is until she gives birth, and Hazrat Ali (may Allah be pleased with him) says that the longer of the two periods will be her waiting period.

17984 - He said: And Ali used to say: The later of the two terms (1).

Hazrat Ali (may Allah be pleased with him) said: The longer of the two periods will be her waiting period (iddah).

Hazrat Amr bin Salim (may Allah have mercy on him) narrates that Hazrat Ubayy bin Ka'b (may Allah be pleased with him) submitted to the Prophet (peace be upon him) that the waiting period ('iddah) of some women has not been mentioned in the Holy Qur'an. Upon this, Allah Almighty revealed this verse of the Holy Qur'an: { وَاللاَّئِی یَئِسْنَ مِنَ الْمَحِیضِ مِنْ نِسَائِکُمْ إنِ ارْتَبْتُمْ فَعِدَّتُہُنَّ ثَلاَثَۃُ أَشْہُرٍ وَاللاَّئِی لَمْ یَحِضْنَ وَأُولاَتُ الأَحْمَالِ أَجَلُہُنَّ أَنْ یَضَعْنَ حَمْلَہُنَّ } (At-Talaq: 4)

Hazrat Ibn Sirin says that I was in the gathering of Hazrat Abdur Rahman bin Abi Laila, may Allah have mercy on him. He said that the waiting period (‘iddah) of a pregnant woman is whichever of the two periods is longer. Upon this, I narrated the account of Hazrat Subai’ah (may Allah be pleased with her) from Hazrat Abdullah bin Utbah (may Allah be pleased with him), so his students began to glare at me. I said that I cannot lie about Hazrat Abdullah bin Utbah (may Allah be pleased with him), as he narrated this in a corner of the mosque.

Hazrat Ibn Abbas (may Allah be pleased with them) says that the waiting period (‘iddah) of a pregnant woman whose husband passes away is whichever of the two periods is longer.

Hazrat Ubaidullah, may Allah have mercy on him, narrates from his father that Hazrat Subai’ah, may Allah be pleased with her, gave birth to a child twenty days or one month after the death of her husband. Abu Sanabil bin Ba’kkak, may Allah be pleased with him, passed by her and said,“Are you ready for marriage? Do not marry until four months and ten days have passed.”She went to the Prophet صلی اللہ علیہ وسلم and related the whole matter, so he said,“You are lawful for marriage.”
