What acts of worship can a woman in her postpartum bleeding (nifas) perform during the month of Ramadan?

A woman experiencing post-natal bleeding (nifas), whether in Ramadan or otherwise, can engage in many acts of worship, including: spending in the way of Allah, feeding those who are fasting, giving charity, remembering Allah by saying 'La ilaha illa Allah' (there is no god but Allah), 'Alhamdulillah' (praise be to Allah), 'Allahu Akbar' (Allah is the greatest), and 'Astaghfirullah' (I seek forgiveness from Allah), seeking knowledge or teaching it, listening to the Quran and reflecting on its meaning, reciting the Quran without touching the Mushaf (physical copy of the Quran), maintaining regular remembrance (adhkar), and supplicating (du'a). However, it is forbidden for her to pray, fast, or stay in the mosque.
