1) From Shaykh Ibn Uthaymeen: There is nothing wrong with seeking out Imams with beautiful voices to increase one's hushoo (proper focus in prayer), so long as that does not lead to neglecting neighborhood mosques, because there is a shar'i interest to be served in the gathering of people of a neighborhood with their Imam.
2) Hadeeth: "Whoever provides food for afasting person to break his fast will have a reward like his." Ibn Taymiyah said: What is meant by providing food means giving him enough to satisfy him. If he cannot give him more than a date or a drink of milk or water, then he should do that and he will have a reward commensurate with his efforts.
3) Do not give zakah to offer food to fasting people, because it should be given to the poor, and some of those who break the fast may not be poor. Do not give it to an orphan unless he is poor, because he may be independent of means due to an inheritance. Servants and drivers must be in genuine need and the one who gives them zakah should not benefit from that.
4) Things that a person keeps for his own uses and needs, such as dwellings, household, furniture, clothing, jewellery, means of transportation, tools of his trade, machinery, equipment, shop decor and so on are not subject to zakah, except for gold and silver.
5) If a Muslim wants to observe i'tikaf for one night, he should enter the mosque before Maghrib and come out after Fajr. The last ten days begin when sun sets on the 20th of Ramadan, at which point the night of the 21st begings. Whoever wants to observe i'tikaf for the ten days or the first of them should enter the mosque before the sun sets.
