Is it obligatory to have the intention for each day of fasting, or is one intention sufficient for the whole month?
The intention is obligatory for each day of Ramadan because each day is an independent act of worship separate from the others.
The intention must be made at night before the break of dawn, as the Prophetﷺ said: "Whoever does not intend fasting at night, there is no fast for him." [An-Nasa’i]
And he also said: "Whoever does not firmly resolve to fast before dawn, there is no fast for him." [At-Tirmidhi, Abu Dawood, and An-Nasa’i]
Whoever wakes up and eats Suhoor while mindful of fasting has made the intention. Likewise, one who firmly intends at any moment during the night to fast the next day has also fulfilled the intention.
What is the ruling on swimming while fasting?
Swimming while fasting is disliked (makruh) due to the risk of water entering the body cavity (jauf) through the nose, ears, or mouth, which would break the fast.
Ramadan is a month of tasbeeh (glorifying Allah), not Sibaha (swimming).
I wish to purchase an online account (a gaming account), and its ownership will be transferred to me. However, my friend will purchase it on my behalf, and I will repay him in deferred installments with an added profit margin to account for the installment sale. What is the ruling of Islamic Law on this transaction?
All praise is due to Allah, and peace and blessings be upon our master, the Messenger of Allah.
The ruling on selling electronic games depends on the ruling of the game itself: if the game is permissible, then selling it is likewise permissible. However, if the game contains Sharia violations that render playing it impermissible, then selling it in that case is neither valid nor permissible. Therefore, we advise the necessity of reviewing the Sharia guidelines for electronic games set forth in Fatwa No. (3369).
Accordingly, if the game is permissible, a person may purchase it, take legal possession of it, and subsequently sell it in deferred installments for a price higher than its purchase price. The General Iftaa' Department has permitted dealing through Murabaha, while emphasizing the necessity of observing the Sharia conditions required for this transaction; please refer to Fatwa No. (2861). And Allah Almighty knows best.
Is it permissible to slaughter a sheep on Eid al-Adha with the intention of charity (sadaqah) on behalf of a sick person, and with the intention of udhiyah (sacrificial animal) at the same time?
Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.
The udhiyah (sacrificial animal) is an act of worship intended for its own sake; therefore, it must be slaughtered with the intention (niyyah) of udhiyah.
Whoever intends to draw closer to Allah through this act of obedience with the intention of udhiyah, and also intends to gift the reward to another person, there is no Islamic objection to that. And Allah Almighty knows best.
