Zienab Mostafa, A prominent Muslim Scholar and Da`iyah based in London, states the following:  “As far as I know, there is no authentic hadith to exclude women who gave birth from the category of sick. However, there are lots of hadiths that acknowledge that women, while pregnant, they have lots of reward on account of what they suffer during that, and when they are in labor, angels protect them and the baby, and whoever dies in labor is considered as martyr.
Islam appreciates women and their role as mothers, and that is why Allah mentioned the kindness we owe to our parents next to the worship of Him. The Prophet (peace and blessings be upon him) recommended being kind to mothers in specific.
Therefore, visiting a woman who recently gave birth is a greatly rewarded action and highly recommended. We need to raise awareness in our communities about that. We can arrange with a group of ladies and bring a scholar to talk about that. If one can write an article about the importance of communication and social ties in general and being kind to women after childbirth, that would be a good idea. May Allah guide us all to the right path.”
