Is the son of the sister by breastfeeding considered a mahram in Islam, and is it permissible for a woman to go for Hajj with him?
Everything that is prohibited by lineage is also prohibited by breastfeeding. The son of the sister by breastfeeding is considered a mahram, just like the son of the sister by blood, and it is permissible for him to be her mahram for Hajj and Umrah. And Allah Knows Best.
What is the ruling on vomiting, and does it invalidate ablution?
Vomit is impure (najis). Its exit is not considered one of the nullifiers of ablution. However, the mouth must be washed and purified from it, and any that gets on clothing or the body must be washed for prayer, because prayer is not valid with impurity present on the body or clothing. And Allah the Almighty 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.
For further reference, see the fatwas: (Fatwas of Shaykh Nūḥ, Fatwa no. 27) and (
248). And Allah Almighty knows best.
