Walid bin Utba, who was the son of Abu Sufyan bin Harb and the governor of Madinah on behalf of his uncle Muawiya, sent me to Ibn Abbas to ask him about how the Messenger of Allah ﷺ performed the prayer for rain.Ibn Abbas replied, "The Messenger of Allah ﷺ went out dressed simply, in humility and submission, until he reached the prayer ground. He ascended the pulpit, but he did not deliver a sermon like the ones you give. Rather, he remained in supplication, humble entreaty, and takbir, then he prayed two rak'ahs just as he would pray for the Eid."
أرسلني الوليد بن عتبة (وهو: ابن أبي سفيان بن حرب وكان أمير المدينة لعمه معاوية) إلى ابن عباس أسأله عن صلاة رسول الله ﷺ في الاستسقاء. فقال: خرج رسول الله ﷺ متبدلا متواضعا متضعا، حتى أتى المصلى، فرقى المنبر، فلم يخطب خطبكم هذه، ولكن لم يزل في الدعاء والتضرع والتكبير، وصلى ركعتين كما يصلي في العيد.
Reported by Abu Dawud (1165), Tirmidhi (558), Nasai (1508), and Ibn Majah (1266), all through Hisham bin Ishaq bin Abdullah bin Kinanah, from his father, and he mentioned it. Ibn Majah added, "in a state of humility, walking calmly." Its chain is hasan because of Hisham bin Ishaq bin Abdullah bin Harith bin Kinanah, of whom Abu Hatim said, "a shaykh," and Ibn Hibban mentioned him among the trustworthy narrators and included his narration in his Sahih. Tirmidhi said, "hasan sahih." It was also reported by Ibn Khuzayma (1408, 1405), Ibn Hibban (2862), Hakim (1/326), and Imam Ahmad (2039), all through this same route, similarly.Hakim said, "This is a hadith whose narrators are from Egypt and Madinah, and I do not know of any of them being attributed to any form of criticism." I say, it is as he said. "Tabadhdhul" means abandoning adornment out of humility.Tirmidhi said, "This is a hasan sahih hadith, and it is the position of Shafii, who said, the prayer for rain is performed like the prayer of the two Eids, saying the takbir seven times in the first rakat and five times in the second, and he cited the hadith of Ibn Abbas as evidence. It is reported from Malik bin Anas that he said, one does not say the takbir in the prayer for rain as one does in the prayer of the two Eids. Numan Abu Hanifa said, the prayer for rain is not to be performed, nor do I instruct people to reverse their cloaks, but rather they should supplicate and then return altogether." End of quote.As for what is reported from Ibn Abbas explicitly stating that the Prophet ﷺ prayed for rain and performed two rakats, reciting in them, saying the takbir seven times in the first and five times in the second, this is extremely daif. It was reported by Bazzar in Kashf Astar (659), and it contains Muhammad bin Abdul-Aziz bin Muhammad bin Umar Zuhri Qurashi, of whom Bukhari and Nasai said, "his hadith is munkar." Ibn Adi gave him a biographical entry in al-Kamil.The description of the prayer for rain, and that it is performed without adhan or iqamah, the majority who hold that the prayer for rain is prescribed did not differ that it is prayed like the Eid prayer, two rakats without adhan or iqamah, and that it begins with the prayer before the sermon, as is established in many hadiths, some of which will follow, since these hadiths are mentioned scattered across different chapters.As for what is reported from Abu Hurairah, who said, the Prophet of Allah ﷺ went out one day to pray for rain, and he led us in two rakats without adhan or iqamah, then he delivered a sermon to us and supplicated to Allah , turning his face toward the qibla with his hands raised, then he turned his cloak inside out, placing the right side on the left and the left side on the right, this is daif. It was reported by Imam Ahmad (8327) from Wahb bin Jareer, who said, my father narrated to us, saying, I heard Numan narrating from Zuhri, from Humayd bin Abdul-Rahman, from Abu Hurairah, and he mentioned it, and Ibn Khuzayma abridged it.This hadith was also reported by Ibn Majah (1268), Ibn Khuzayma (1409), and Bayhaqi (3/347), all through the route of Wahb bin Jareer, similarly. Bayhaqi said, "Numan bin Rashid alone narrated it from Zuhri," which indicates that he considered it weak, though in al-Khilafiyat he said, "its narrators are trustworthy." I say, there is something questionable in his statement "its narrators are trustworthy," for Numan, who is Ibn Rashid al-Jazari, Abu Ishaq al-Raqqi, was declared daif by most of the imams. Yahya bin Saeed said, "extremely daif." Ahmad said, "his hadith is confused, he narrated munkar hadiths." Abu Dawud said, "daif." Nasai said, "daif, makes many errors," and in another place he said, "his hadiths are inverted." As for Ibn Main, it is reported from him both "daif" and "trustworthy," but most of his students transmitted from him that he considered him daif.Ibn Khuzayma reported it in another place in detail (1422), with this wording, that the Prophet ﷺ went out one day to pray for rain, and he led us in two rakats without adhan or iqamah, he said, then he delivered a sermon to us and supplicated to Allah, turning his face toward the qibla with his hands raised, then he turned his cloak inside out, placing the right side on the left and the left side on the right. Then Ibn Khuzayma said, "There is doubt regarding Numan bin Rashid, for there is much confusion in his narration from Zuhri. If this report is established, it indicates that the Prophet ﷺ delivered the sermon, supplicated, and turned his cloak inside out twice, once before the prayer and once after it."I say, as for his statement, "he delivered the sermon, supplicated, and turned his cloak inside out twice," this is not clear from the text of the hadith.
