Silsilat al-Ahadith al-Sahihah

Abu Hazim says: I was behind Sayyiduna Abu Hurairah (may Allah be pleased with him), he performed ablution for prayer, and (while washing his arms) he extended his hand up to the armpits. I said: Abu Hurairah! What kind of ablution is this? He said: Banu Farukh! Are you also present here? If I had known that you people were here, I would not have performed ablution in this manner. I have heard my beloved (Prophet) (peace and blessings be upon him) say: "The adornment of a believer will reach as far as the water of ablution reaches."
