أحسن الله إليكم. According to Sh al-Islām and Sh Ibn Uthaymīn (رحمهما الله), if there is no fixed duration for travel, is it based on urf? Ex: If someone lives 4,000 km from his parents and stays with them for two weeks, would he still be considered a musāfir and given the rukhaṣ? بارك الله فيكم

Ustadh AbdulAziz al-Haqqan

If you travel to another country to stay for two weeks and come back, yes. According to the saying of Shaykh Ibn Taymiyyah and Ibn Uthaymin, you are still a traveler and you can take the rukhas (concessions). This is the correct saying, Insha'Allah.
