As Salaamu Alaikum Wa Rahmatullahi Wa Barakatuh,

Based on your specific question and information provided.

The Islamic Scholars have divided the Islamic teachings in three parts. (1) Fundamental of Faith (Belief / Aqidah), (2) Islamic Ethics / Morals, and (3) Islamic Law/ Fiqh / Jurisprudence.

It is recommended ( Mustahab) to be in the state of ritual purity all the time ( in Wadhu). A Believer can take precaution (ihtiyat), based on Belief, etiquette, respect, reverence …. What is permissible and what is preferred or optimal are two different things. Jurisprudence Rules are one aspect of Islamic teachings derived by the fallible Jurists and are minimum requirements.

From the Jurisprudence Perspective: 

Ruling 448. Certain things are unlawful for a ḥāʾiḍ:

1. to perform those ritual acts of worship that must be performed with wuḍūʾ, ghusl, or tayammum – such as prayers – if she does so with the intention of performing a valid act. However, there is no problem if she performs ritual acts of worship for which wuḍūʾ, ghusl, or tayammum is not necessary, such as ṣalāt al-mayyit;
2. all the things that are unlawful for a junub, as mentioned in the rules of janābah;

Ruling 354. Five things are unlawful for a junub:

1. touching the writing of the Qur’an with any part of the body, or the name of Allah in whichever language it may be written; and it is better not to touch the names of Prophets, Imams, and Her Eminence [Fāṭimah] al-Zahrāʾ (peace be upon them) as well;
2. entering Masjid al-Ḥarām and the Mosque of the Prophet (Ṣ), even to the extent of entering from one door and exiting from another;
3. staying in other mosques; and similarly, based on obligatory precaution, staying in the shrines of the Imams (ʿA). However, there is no problem if a junub passes through a mosque; for example, by entering from one door and exiting from another;
4. entering a mosque in order to take something from it; and similarly, based on obligatory precaution, placing something in it even if he does not enter the mosque himself [but places something in it from outside];
5. reciting any of the verses for which sajdah is obligatory. These verses are found in four chapters (surahs) of the Qur’an:
a. Sūrat al-Sajdah (Chapter 32), verse 15;
b. Sūrat Fuṣṣilat (Chapter 41), verse 37;
c. Sūrat al-Najm (Chapter 53), verse 62;
d. Sūrat al-ʿAlaq (Chapter 96), verse 19.
