Prayer: A Nomad Travelling for Ziyarah, Hajj, or Business and the Seventh Condition: Frequent Traveller
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 1292
If a nomad travels for ziyārah,[1] hajj, business, or suchlike, and it cannot be said that he is travelling with his house, he must perform qaṣr prayers; and if it can be said, then he must perform tamām prayers.
Seventh condition: one must not be a frequent traveller (kathīr al‑safar). [The frequent traveller is of two kinds:] 1) someone whose profession is travelling – such as a driver and the captain of a ship, or a delivery person or shepherd – and 2) someone who frequently travels even though his work does not require him to do so – such as someone who travels three days in a week even if it is for recreational and touristic purposes – such a person must perform tamām prayers.
-Ayatullah Sistani, Practical Laws of Islam, Prayer (Salah)
Ziyārah is a visitation to the place of burial of a holy personality or a holy place.
