Yes, it is permissible to pray for mercy upon them.
And Allah Almighty knows best.
Is it valid to perform the obligatory prayer while sitting?
Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.
Standing (Al-Qiyam) while having the ability to do so is one of the pillars (Arkan) of the prayer; the obligatory (Faridah) prayer is not valid without it. However, whoever is unable to stand may pray sitting down. As for voluntary (Nafilah) prayers, it is permissible to pray them sitting even if one is able to stand, but the one sitting receives half the reward of the one who prays standing. And Allah the Exalted knows best.
Is it obligatory to have an intention (niyyah) for every prayer?
Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.
It is obligatory for the worshiper to have a specific intention (Niyyah) for every prayer, meaning they must consciously intend the act of worship they are performing. The intention is a pillar (Rukn) of the prayer, and the prayer is not valid without it. It is not a requirement to utter the intention verbally; rather, doing so is considered a recommended Sunnah. And Allah the Exalted knows best.
What is the ruling on reciting the Noble Qur’an during menstruation?
All praise is due to Allah, and peace and blessings be upon our master, the Messenger of Allah.
It is impermissible for a woman in menses, a woman in postnatal bleeding, or a person in a state of major ritual impurity to recite any part of the Noble Qur’an with the intention of recitation, even from a mobile phone or a computer, and even if the recitation is from memory. It is narrated on the authority of ʿAlī ibn Abī Ṭālib (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) “was not prevented, or he said kept back, from the Qur’an by anything except janābah (major ritual impurity).” It was narrated by Abū Dāwūd and al-Tirmidhī, who said: “Ḥasan ṣaḥīḥ.”
Janābah and menstruation are one and the same in that both constitute a major ritual impurity. Just as a woman is commanded by Allah Almighty to pray, fast, and recite the Noble Qur’an during her period of purity, she is likewise commanded to refrain from these during the period of her excuse.
