An Arabi stood up and urinated in the mosque. The people grabbed at him, but the Prophet ﷺ said to them, "Leave him alone, and pour a bucket of water, or a pail of water, over his urine. You have been sent only to make things easy, not to make things difficult."
قام أعرابي فبال في المسجد، فتناوله الناس، فقال لهم النبي ﷺ: دعوه! وهريقوا على بوله سجلا من ماء، أو ذنوبا من ماء؛ فإنما بعثتم ميسرين، ولم تبعثوا ميسرين.
Bukhari narrated it in the chapter on wudu (220) from Abu Yaman, who said, Shuayb informed us, from Zuhri, who said, Ubaydullah bin Abdullah bin Utba bin Masud informed us, that Abu Hurairah said... and then he narrated it. In another version with him (6128), the people rushed at him to attack him, and the Messenger of Allah ﷺ spoke, and he narrated the hadith, in which it reads, "pour water over his urine" instead of "pour."He added, in the book of manners (6010), Abu Hurairah said, the Messenger of Allah ﷺ stood in prayer and we stood with him, and a bedouin, while still in prayer, said, "O Allah, have mercy on me and on Muhammad, and have mercy on no one else besides us." When the Messenger of Allah ﷺ finished the prayer with the greeting of peace, he said to the bedouin, "You have narrowed something vast," meaning the mercy of Allah. This is how Bukhari narrated it through the route of Shuayb, from Zuhri, who said, Abu Salama bin Abdul-Rahman informed me that Abu Hurairah said this. He did not mention in it the bedouin's urinating.Abu Dawud (380), Tirmidhi (147), and Nasai (3-14) all narrated it through the route of Sufyan, from Zuhri, from Saeed bin Musayab, from Abu Hurairah, and they added, he had not been there long before he urinated in the masjid, so the people rushed toward him, but the Prophet forbade them. They then narrated the rest of the hadith.Ibn Majah (529) narrated something close to it through the route of Muhammad bin Amr, from Abu Salama, from Abu Hurairah, in which it reads, a bedouin entered the masjid while the Messenger of Allah ﷺ was sitting, and he said, "O Allah, forgive me and Muhammad, and forgive no one else besides us." The Messenger of Allah ﷺ laughed and said, "You have fenced in something vast." Then he turned away, and when he was in a corner of the masjid, he squatted down and urinated. The bedouin said, after he had come to understand, "He came toward me, may my father and mother be sacrificed for him! Yet he neither scolded me nor cursed me." In this chain is Muhammad bin Amr bin Alqama, who is trustworthy (saduq).His saying "ihtajarta" means, you have constricted what Allah has made spacious, and it carries the same meaning as "hajarta."As for his saying "hariqu," Hafiz said in Fath al-Bari (1/303), "This is how most transmit it, while in the version of Asili it reads 'aharyqu,' with an added hamza. Ibn Tin said, it is with the ha silent, and it has been related from Sibawayh that he said, 'ahraqa yuhriqu ihraqan,' like 'astaa yastee istiaan,' with the alif detached and given a fatha in the past tense, and the ya given a damma in the future tense. This is a dialectal variant of 'ataa yutee,' where the seen and the ha were substituted in place of the lost vowel movement of the middle letter of the verb. It has also been transmitted with the ha given a fatha, though this has been questioned as problematic. It can be explained on the basis that the ha is substituted for the hamza, since the original form of 'haraqa' is 'araqa,' after which the hamza was introduced, so the movement placed on the ha preserves both the substituted letter and the letter it was substituted from, and there are parallel cases for this. Jawhari mentioned another explanation, namely that its origin is 'ariqu,' and the second hamza was then changed to a ha for ease of pronunciation. Thalab, in al-Fasih, stated decisively that 'ahriqhu' takes a fatha on the ha." End of quote.
