Narrated ‘Abdullah bin Zaid (rad):

Two thirds of a Mudd (of water) was brought to he Prophet (ﷺ) (for ablution) so he began rubbing his arms. [Reported by Ahmed, and Ibn Khuzaima graded it Sahih].

وَعَنْ عَبْدِ اَللَّهِ بْنِ زَيْدٍ ‏- رضى الله عنه ‏- { أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-أَتَى بِثُلُثَيْ مُدٍّ, فَجَعَلَ يَدْلُكُ ذِرَاعَيْهِ } أَخْرَجَهُ أَحْمَدُ, وَصَحَّحَهُ اِبْنُ خُزَيْمَة َ [1]‏ .‏
