عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَتَوَضَّأُ بِإِنَاءٍ يَكُونُ رِطْلَيْنِ وَيَغْتَسِلُ بِالصَّاعِ
It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to perform ablution with a vessel containing two ritls of water and would perform ghusl with one sa’ of water.
