Taraweeh and Tahajud During Ramadhan

In reality Taraweeh, Tahajjud and Qiyaam of Ramadhaan, are all one and the same thing. The long hadeeth of Abu Dharr (RA) in Ibn Maajah is clear evidence of this statement. The summary of the hadeeth is that Abu Dharr (RA) said,
“We kept the fasts of Ramadhaan with the Messenger of Allaah (SAW), then he led us in Qiyaam (Taraweeh prayer) on the 23rd night (when seven nights were left) till about one third of it passed. He did not observe it on the 24th, then on the 25th night he led us till about half the night passed. We requested to offer supererogatory prayer during the whole night. The Messenger of Allaah (SAW) said, “He who observes Qiyaam along with the Imaam till he finishes it, then it is as if he offered prayer the whole night.” Then he did not observe the Qiyaam with us on the 26th night, then finally on the 27th night he gathered his wives, members of his household and the people and he led everyone in the Qiyaam (Taraweeh prayer) till we feared of missing the dawn meal.” [Ibn Maajah (no. 1327)]
It is clear from this narration that the Messenger of Allaah (SAW) led the taraweeh prayer in three parts of the night and by praying it after Eesha until the end of the night he informed us of its time. It is likely that no time would have remained for tahajjud, (as taraweeh on the 27th night was prayed so late in the night to the extent that there were fears of missing the dawn meal) therefore no doubt remains about taraweeh and tahajjud being one prayer.

Maulana Muhammad Anwar Shah Kashmiree Deobandee said,
“There is no way out or alternative in accepting that the taraweeh of the Messenger of Allaah (SAW) was eight (8) rak’ahs (units), and it is not established by any narration he prayed taraweeh and tahajjud separately.” [Urf ash-Shadhee (1/166)] [2]
Praying taraweeh or tahajjud with congregation, or alone in the mosque or in the house in the latter part of the night is more virtuous. Umar (radi-Allaahu ’anhu) said,
“Praying it late at night when you go to sleep is more virtuous than praying in the first part of the night.”
During this era of laziness and excuses; the taraweeh should be prayed with the congregation otherwise many people will leave and abandon it. Never mind listening to the whole Qur’aan they will not even hear the Qur’aan at all!During the Khaliphate of Umar (radi-Allaahu ’anhu) taraweeh was prayed at the earlier time with congregation and the Messenger of Allaah (sal-Allaahu ‘alayhe wa sallam) also prayed in the first part of the night during the first night (on the 23rd night).
