Salat al Musafir, Prayers said by a traveller

Salat al Musafir.—Prayers said by a traveller. A person who makes a journey which lasts three days or three nights is, for this purpose, considered a traveller. The length of a day's journey is estimated at the distance a camel can march in that period of time. If a traveller intends to stay in a certain place fifteen days, he must repeat the usual Namáz; if less than fifteen days, or when actually on the journey, he can shorten it. He is then permitted to say only two farz rak'ats. He may omit the sunnat and nafl rak'ats if he chooses; but the three witr rak'ats he must recite at the Salat-ul-'Ishá. If a traveller passing through a place is, for the time being, the most suitable person to act as Imám, he being a traveller will only recite two rak'ats. The rest of the worshippers then complete the Namáz. In the case where a permanent resident of the place is the Imám and the traveller only a worshipper, the Imám is bound to recite the whole number of rak'ats and the traveller must also repeat the whole after him. The principle on which this is based is that the worshippers must not recite less than the Imám.
