"the two waters meet, and if the woman's water overcomes the man's water, she becomes feminine, and if the man's water overcomes the woman's water, she becomes masculine." They said: You have spoken the truth, so inform us about thunder, what is it? He mentioned it. The addition between the brackets is found in al-Ḍiyāʾ's narration, and it was also narrated by Ibn Mandah in "al-Tawḥīd" (folios 21-22), who said: "This is a connected isnād and its narrators are well-known trustworthy individuals, and it was also reported by al-Nasāʾī." I said: meaning in "al-Sunan al-Kubrā" as al-Ḥāfiẓ al-Mizzī clarified in "al-Tuḥfah" (4/394). Al-Tirmidhī said: "A good, authentic, and rare ḥadīth." Abū Nuʿaym said: "Rare from the narration of Saʿīd, unique to Bukayr." I said: and he is trustworthy as al-Dhahabī mentioned in "al-Mīzān," and perhaps his basis for this is Abū Ḥātim's statement about him: "A shaykh." Along with Ibn Ḥibbān's inclusion of him in "al-Thiqāt," and the authentication by those who authenticated this ḥadīth among those we mentioned. As for al-Ḥāfiẓ, he said in "al-Taqrīb": "Acceptable." Meaning when corroborated, and he was not corroborated as Abū Nuʿaym explicitly stated in his previous statement, so according to al-Ḥāfiẓ, the ḥadīth is lenient, and it is more likely to be authentic as the group believed, especially since al-Ḥāfiẓ mentioned a supporting witness for it in "Takhrīj al-Kashshāf" (p. 91) from the narration of al-Ṭabarānī in "al-Awsaṭ" from Abū ʿImrān al-Kūfī from Ibn Jurayj from ʿAṭāʾ from Jābir that Khuzaymah ibn Thābit—not the Anṣārī—asked the Prophet (ṣallá Allāhu ʿalayhi wa-sallam) about thunder? He said: "It is an angel with a whip in his hand, when he raises it, it flashes, when he rebukes, it thunders, and when he strikes, it causes a shock."
