Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 11
وَ قَالَ عَلِيٌّ عَلَيْهِ اَلسَّلاَمُ: "اَلْمُضَارِبُ مَا أَنْفَقَ فِي سَفَرِهِ فَهُوَ مِنْ جَمْعِ اَلْمَالِ فَإِذَا قَدِمَ بَلْدَتَهُ فَمَا أَنْفَقَ فَهُوَ مِنْ نَصِيبِهِ".
Imam Ali ibn Abi Talib عليه السلام said: "Whatever the partner spends during his travel is taken from the joint capital. However, when he returns to his town, whatever he spends is from his own share."
