When is supplication (du‘a) more likely to be accepted: before or after breaking the fast in Ramadan?
Du‘a is accepted at all times, and this is part of Allah’s mercy and generosity toward His servants.
The Prophet ﷺ said: "No Muslim makes a supplication that does not involve sin or severing family ties except that Allah grants them one of three things: either He grants their supplication immediately, or He stores it for them in the Hereafter, or He averts from them an equivalent harm." [Narrated by Ahmad]
However, in Ramadan, du‘a is especially likely to be accepted shortly before breaking the fast.
The Prophet ﷺ said: "Three supplications are never rejected: the supplication of a fasting person until they break their fast, the supplication of a just leader, and the supplication of an oppressed person. Allah raises it above the clouds, opens the gates of heaven for it, and says: ‘By My might, I will surely grant you victory, even if after a while.’" [Narrated by Al-Tirmidhi]
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.
