8 Abu Hurayrah (may Allah be pleased with him) said: The Messenger of Allah, peace and blessings be upon him, declared, “The purification of any one of your vessels when a dog has lapped in it is to wash it seven times, the first of them with earth.” Recorded by Muslim.

In another wording of Muslim: “let him pour it out,” and al-Tirmidhi has: “the last of them, or the first of them.” (1)

Vocabulary of the ḥadith
• ṭuhūr —with ḍamma on the ṭāʾ, which is the more common reading. Al-Nawawi said: The majority of linguists maintain that both ṭuhūr and wuḍūʾ are pronounced with ḍamma when the verbal noun (the act of purification) is meant, and with fatḥa when what is meant is the water used for purification; here the verbal noun is intended.
• walaġa — conjugates like fataḥa, ḥasiba, waritha. Its imperfect is yalagh, with the middle root letter vocalised either with fatḥa or kasra; one also says yālagh. Al-wulūgh means lapping with the tip of the tongue, which is how a dog and other beasts drink.
• akhrahunna — written with a final alif that represents the feminine ending. The plurals of ukhrā are ukhriyyāt and ukhar, just as from kubrā one gets kubrayyāt and kubar. Here it means “one of them,” as appears in some narrations of this ḥadith.
• turāb — the fine surface soil of the earth.
• falyurriqhu — that is, let him pour it out onto the ground. Al-Miṣbāḥ says: rāqa (of water and the like) means “to flow”; with the hamza it becomes arāqahu (“he poured it out”). The hamza may be changed to a hāʾ, giving harāqahu; both letters may even be combined, producing ahrāqahu, yuhriquhu, with the hāʾ silent.
• awlahunna — “akhrahunna” or “ūlahunna”: the stronger view is that this uncertainty comes from the transmitter, and not
