Praying Tarawih is recommended for the traveller as for the non-traveller because Prophet Muhammad (peace and blessings of Allah be upon him) persisted in praying qiyam al-layl whether he was travelling or not.

There is nothing wrong with reading from the Mus-haf in Tarawih prayer. `Aishah (may Allah be pleased with her) had a slave who used to lead her in prayer in Ramadan, reading from the Mus-haf.

During the time of `Umar ibn Al-Khattab, the Tarawih prayer was commonly performed in 20 Rak`ahs, with some narrations mentioning 21 or 23 including Witr. However, the number of Rak`ahs in Tarawih remains flexible, as there is no fixed limit in Islamic teachings.

Witr prayer is a confirmed sunnah according to the majority of scholars. Whoever omits to pray Witr deliberately is a bad man, whose testimony should not be accepted.
