Q) My work hours begin before the imam finishes taraweeh prayer, and I need to go to work. What should I do?
A) Praise be to Allaah.
Pray whatever you can of taraaweeh in congregation with the imam. It does not matter if you leave for work after two or four or six rak’ahs, etc. Then complete the prayer at home and pray witr at the end.
If you find a mosque that prays early and you can complete the prayer with them and then go to work, this is better, because the Prophet (peace and blessings of Allaah be upon him) said: “Whoever prays qiyaam with the imam until he finishes, it will be written that he spent the whole night in prayer.” Narrated by al-Tirmidhi, 806; classed as saheeh by al-Albaani in Saheeh al-Tirmidhi.
And Allaah knows best.
