A man said: Messenger of Allah, allow tourism for me. The Prophet ﷺ said: The tourism of my people is striving in the path of Allah, the Exalted. (Using translation from Abū Dāʾūd 2486)
أَنَّ رَجُلًا قَالَ يَا رَسُولَ اللهِ ائْذَنْ لِي فِي السِّيَاحَةِ فَقَالَ إِنَّ سِيَاحَةَ أُمَّتِي الْجِهَادُ فِي سَبِيلِ اللهِ
