Is it valid to perform Tarawih prayer at home?
It is Sunnah for a Muslim to perform Tarawih prayer in congregation at the mosque.
However, if a person sometimes prays it at home in congregation with their family for a valid reason, there is no harm in doing so.
What does (Whoever fasts Ramadan with faith and seeking reward) mean?
This phrase is part of a hadith in which the Prophet ﷺ said:
"Whoever fasts Ramadan with faith and seeks his reward from Allah, their past sins will be forgiven." [Agreed upon]
The meaning is:
● They fast Ramadan with firm belief that Allah has made it obligatory.
● They fast out of obedience to Allah, knowing they will meet Him.
● They hope for reward from Allah and fast purely out of their faith while seeking His reward.
Should a prayer performer who forgets to offer the middle Tashahod (saying ash-hadu anala ilaha ila-alah) offer Sujood As-Sahw (prostration of forgetfulness)?
He/she should offer two prostrations of forgetfulness at the end of the prayer. And Allah Knows Best.
How is the beginning of Ramadan determined?
1. Completing 30 days of Sha‘ban, or
2. Sighting the crescent moon after sunset on the 29th day of Sha‘ban.
It is Sunnah to search for the moon, and it is obligatory to follow the official authorities responsible for announcing it.
