Encyclopedia of Prophetic Hadiths

The Messenger of Allah (ﷺ) used to perform Ghusl (ritual bath) from Janābah (major ritual impurity) using one Sā‘ of water, and he would perform Wudū’ (ablution) with one Mudd.

The Prophet (may Allah's peace and blessings be upon him) used to take a ritual bath with one Sā‘ up to five Mudds, and he used to perform ablution with one Mudd.

"There is no Muslim who performs ablution well and then stands and prays two Rak‘ahs while focused on them with his heart and his face, except that Paradise will be guaranteed for him." I said: "What a fine thing this is!" Thereupon, I heard someone in front of me saying: "What he said before it was even finer." I looked and it was ‘Umar ibn al-Khattāb, who said: "I see that you have just come." He said: "If anyone of you performs ablution thoroughly and then says, 'I bear witness that there is no god but Allah and that Muhammad is the servant and Messenger of Allah', the eight gates of Paradise will be opened for him and he may enter from whichever of them he wishes."
