"عَنْ عَائِشَةَ بنْتِ قُدَامَةَ بْنِ مَظْعُونٍ، عَنْ أَبِيهَا عَنْ أَخِيهِ عُثْمَانَ بْنِ مَظْعُونٍ أَنَّهُ قَالَ: يَا رَسُولَ الله إِنِّى رَجُلٌ يَشُقُّ عَلَىَّ هَذِهِ الْغربَةُ في المَغَازى، أَفَتَأذَنُ لِى في الْخِصَاءِ فَأَخْتَصِى؟ فَقَالَ: لا، عَلَيْكَ يَابْنَ مَظْعُونٍ بِالصِّيامِ فَإِنَّهُ مَجْفَرَةٌ".

[Machine] He said, "O Messenger of Allah, I am a man who struggles with this village in battles. So may I be allowed to seek privacy and abstain (from others)?" He (the Prophet) said, "No, but you, O son of Mazh'un, should take up fasting, for it is a shield."
