Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: Thumamah bin Uthal (the narrator is in doubt; perhaps the words are: Uthalah) accepted Islam, so the Prophet (peace and blessings be upon him) said: Take him to the garden of Banu so-and-so, and instruct him to take a ritual bath (ghusl).
Imam Ahmad and Imam al-Bazzar recorded it, and he (al-Bazzar) recorded these additional words in it: With water and lote-tree leaves (let him take the ritual bath).

The chain of Imam Ahmad and Imam al-Bazzar contains a narrator, Abdullah bin Umar al-Umari, whom Yahya bin Ma'in and Abu Ahmad bin Adi declared "thiqah (trustworthy)"; others besides these two declared him "da'if (weak)", but without attributing lying to him. Imam Abu Ya'la said (in his chain): from a man, from Sa'id al-Maqburi. (Al-Haythami says:) If he is al-Umari, then the hadith is hasan (good); and Allah knows best.
