During the month of Ramadan, Muslims are required to fast from dawn to sunset. The act of giving Zakat al-Fitr, also known as Fitrana or Fitr charity, is mandatory before the end of Ramadan. It is a charitable donation given to the less fortunate to purify one's fast and to help those in need. Therefore, the correct answer "ഫിത്ർ സകാത്ത്" (Zakat al-Fitr) aligns with the requirement to give charity during the end of Ramadan.
