Muwatta Malik, Book 21, Hadith 975 (In-Book)

Yahya related to me from Malik from Yahya ibn Said that Said ibn al-Musayyab used to say, "When a man is given something to use in a military expedition, and he brings it to the battlefield, it is his." Malik was asked about a man who pledged himself to go on a military campaign, equipped himself,and when he wanted to go out, one or both of his parents prevented him. He said, "He should not contradict them. Let him put it off for another year. As for the equipment, I think that he should store it until he needs it. If he fears that it will spoil, let him sell it and keep its price so that he can readily buy what is needed fora military expedition. If he is well-to-do, he will find the like of his equipment when he goes out, so let him do what he likes with his equipment."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، أَنَّ سَعِيدَ بْنَ الْمُسَيَّبِ، كَانَ يَقُولُ إِذَا أُعْطِيَ الرَّجُلُ الشَّىْءَ فِي الْغَزْوِ فَيَبْلُغُ بِهِ رَأْسَ مَغْزَاتِهِ فَهُوَ لَهُ ‏.‏ وَسُئِلَ مَالِكٌ عَنْ رَجُلٍ أَوْجَبَ عَلَى نَفْسِهِ الْغَزْوَ فَتَجَهَّزَ حَتَّى إِذَا أَرَادَ أَنْ يَخْرُجَ مَنَعَهُ أَبَوَاهُ أَوْ أَحَدُهُمَا فَقَالَ لاَ يُكَابِرْهُمَا وَلَكِنْ يُؤَخِّرُ ذَلِكَ إِلَى عَامٍ آخَرَ فَأَمَّا الْجِهَازُ فَإِنِّي أَرَى أَنْ يَرْفَعَهُ حَتَّى يَخْرُجَ بِهِ فَإِنْ خَشِيَ أَنْ يَفْسُدَ بَاعَهُ وَأَمْسَكَ ثَمَنَهُ حَتَّى يَشْتَرِيَ بِهِ مَا يُصْلِحُهُ لِلْغَزْوِ فَإِنْ كَانَ مُوسِرًا يَجِدُ مِثْلَ جِهَازِهِ إِذَا خَرَجَ فَلْيَصْنَعْ بِجِهَازِهِ مَا شَاءَ ‏.‏
