Narrated by Aisha, who said: The Messenger of Allah (peace and blessings be upon him) used to eat watermelon with fresh dates, saying: "We counteract the heat of this with the coolness of this, and the coolness of this with the heat of this."(1)

3837 - Muhammad ibn al-Wazir narrated to us, al-Walid ibn Mazid narrated to us, I heard Ibn Jabir, Sulaym ibn Amir narrated to me, from the two sons of Busr al-Sulamiyyin, who said: The Messenger of Allah (peace and blessings be upon him) entered upon us, and we presented him with clarified butter and dates, and he loved clarified butter and dates.(2)

(1) Its chain is good, because of Sa'id ibn Nusayr — who is al-Baghdadi, then al-Raqqi — for he is truthful and there is no harm in him. Urwah: he is Ibn al-Zubayr ibn al-Awwam, and Abu Usamah: he is Hammad ibn Usamah.
It was also recorded by al-Tirmidhi (1949), and al-Nasa'i in "al-Kubra" (6688) via the route of Sufyan al-Thawri, and al-Nasa'i (6687) via the route of Ibrahim ibn Humayd al-Ru'asi, both from Hisham ibn Urwah, with it, without his saying: "We counteract the heat of this..."
It was also recorded by al-Nasa'i in "al-Kubra" (6693) via the route of Yazid ibn Rumman, from al-Zuhri, from Urwah, from Aisha, without his saying: "We counteract the heat of this..." Al-Nasa'i said, as quoted from him by al-Mizzi in "Tuhfat al-Ashraf" 12/101: It is not preserved from the hadith of al-Zuhri.
It is in "Sahih Ibn Hibban" (5246) and (5247), without his saying: "We counteract the heat of this..."
His saying: al-tibikh — we have established it from (A), (J), and (H), and in (B): al-bittikh, and al-tibikh is a dialectal variant of al-bittikh (watermelon).
Al-Khattabi said: In it is the affirmation of medicine and treatment, and countering a harmful thing with its opposite in nature, according to the method of medicine and treatment, and in it is the permissibility of enjoying a variety of foods and partaking of permissible pleasures.
(2) Its chain is authentic. Ibn Jabir: he is Abd al-Rahman ibn Yazid ibn Jabir al-Dimashqi.
It was also recorded by Ibn Majah (3334) via the route of Sadaqah ibn Khalid, from Abd al-Rahman ibn Yazid ibn Jabir, with it. =
