Virtues of Pregnancy,1, When a woman is pregnant with a child, all the angels will make repentence on her behalf. Allah will, for each day of her pregnancy, write for her 1000 good deeds and erase from her 1000 bad deeds. 2, When a pregnant woman starts to feel the pain from contractions, Allah will write in her records as someone who is doing jihad (spiritual or physical struggle) in His path. 3, When a woman becomes pregnant by her husband and he is pleased with her, she obtains the reward of a person engaging in fasting for Allah and a person spending the night in worship, 4, A woman from the time of pregnancy until childbirth and weaning the baby, is like the Mujahidm, who is stationed on the frontiers of the Islamic land. If she dies during this period, she dies the death of a shahid (martyr). 5, Two raka'at salaat performed by a pregnant woman is better than 80 raka'at salaat performed by a non-pregnant woman. 6, A woman who is pregnant gets the reward of fasting during the day and of doing worship during the nights. 7, A woman who gives birth gets the reward of 70 years of salaat (prayer) and fasting. For each vein that feels pain, Allah SWT gives her the reward of one accepted hajj (Pilgrimage to Makkah). If the woman dies within 40 days of giving birth, she will die as a shahid (matyr). 8, Hadith)......."A woman that dies in her virginity or during her pregnancy or at the time of birth or thereafter (in nifaas) will attain the rank of a martyr". 9, Nabi(salalaallahu alayhi wassallam) is reported to have also said ".......When her labour pains commence, the inhabitants of the earth and the sky are unaware of the stores of comfort that are prepared for her. When she delivers and breast feeds her child, then she will be granted a reword for every gulp of milk, if she had to remain awake during the night for the sake of the child,she will receive the reword of emancipating seventy slaves in the path of Allah.Is this all in quran & Sunnah or not please clarify?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

What you mentioned in the question is neither stated in the Quran nor in the well-known books of Sunnah, with the exception of the death of a pregnant woman or a virgin woman. However, a fabricated narration is reported in this regard with the wording: “when a woman becomes pregnant, she gets the reward of a person who fasts during the day and performs the optional night prayers, who is obedient and humble before Allaah and who strives in the path of Allaah. When she gets labour contractions, no creature knows the reward she gets for this, and when she gives birth, for each child she delivers, she gets the reward of freeing a slave.” Al-Albaani classified this narration among the fabricated narrations. The scholars said: “If you see that a narration is not found in the well-known Islamic books and resources, then be sure that it is fabricated.”

As regards the death of a pregnant woman, it is reported in an authentic narration that a woman who dies during her pregnancy or as a virgin is martyr.

Allaah Knows best.
