Pray as much as posible.

The last ten days of Ramadan are considered highly blessed, especially the 27th night which is called laylat al-qadr – the “Night of Power,” or the “Night of Destiny.” It is believed that on this night the prophet Muhammed received the first revelation of the Qur’an. For many Muslims, this 10-day period is marked by a heightened spiritual intensity, and they may spend these nights praying and reciting the Qur’an.

After 30 days of fasting, the end of the month of Ramadan is observed with a day of celebration called Eid-ul-Fitr. On this day, Muslims gather in one place to offer a prayer of thanks. It is traditional to wear new clothes, visit friends and relatives, exchange gifts, eat delicious dishes prepared for this occasion, and wait patiently for the next year.
