What is the ruling on congratulating others on the arrival of Ramadan?
Congratulating others on the arrival of Ramadan is permissible.
If someone does it to express their love for worship and the blessings of Ramadan, and congratulates their fellow Muslim, they have done something good.
The Prophet ﷺ said: "Shall I not tell you something that, if you do it, you will love one another? Spread peace (Salam) among yourselves." [Narrated by Muslim]
Giving Salam is a prayer for peace and safety.
Is it permissible for a young man and a young woman to enter into a covenant as a married couple without having a true seclusion (Khalwah) until their marriage contract is officially concluded?
The relation which isn`t based on a marriage contract is forbidden, and entering into a covenant as a married couple is unaccounted for and is from the evil suggestions of the devil.
What is the ruling of Islamic Law on supplicating with other than the transmitted (Ma'thur) supplications in prayer?
All praise is due to Allah, and peace and blessings be upon our master, the Messenger of Allah.
It is permissible to supplicate (make du'a) during the prayer for anything from the affairs of religion or worldly life, and the prayer is not invalidated by doing so.
Shaykh al-Islam, the Imam an-Nawawi, may Allah have mercy on him, says: "Our madhhab [i.e., the Shafi'i madhhab] holds that it is permissible for a person to supplicate during it [the prayer] with anything that is permissible to supplicate with outside the prayer, from the affairs of religion or worldly life. He may say: 'O Allah, grant me wholesome sustenance, offspring, a house, and a beautiful young wife' — describing her; or: 'O Allah, free so-and-so from prison,' or 'destroy so-and-so,' and other such things — and none of this invalidates his prayer according to us. And this is also the view of Malik, ath-Thawri, Abu Thawr, and Ishaq." [Al-Majmu', Vol.3/P.454]. 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.
For further reference, see the fatwas: (Fatwas of Shaykh Nūḥ, Fatwa no. 27) and (
248). And Allah Almighty knows best.
