Tahajjud is a special night prayer performed by Muslims. It is considered to be one of the most virtuous and rewarding acts of worship, and is believed to bring about immense spiritual benefits.
The time for Tahajjud begins after midnight and lasts until the pre-dawn period. The ideal time to perform Tahajjud is during the last third of the night. Muslims are encouraged to wake up during this time and offer two or more rak’ahs (units) of prayer.
