3378 - Al-Hasan ibn 'Ali narrated to us, 'Abd al-Razzaq narrated to us, Ma'mar informed us, from al-Zuhri, from 'Ata' ibn Yazid al-Laythi, from Abu Sa'id al-Khudri, from the Prophet, peace and blessings be upon him, this same hadith, with the addition: "And al-ishtimal al-samma' (the covering of the samma') is that a man wraps himself in a single garment, placing the two ends of the garment on his left shoulder and exposing his right side. And al-munabadha (the throwing) is that he says: 'When I throw this garment to you, the sale has become binding.' And al-mulamasah (the touching) is that he touches it with his hand without spreading it out or turning it over, and when he touches it, the sale becomes binding."

=============================================

Al-Khattabi said: "Al-mulamasah is that you touch the garment you wish to buy, meaning: he touches it with his hand without spreading it out or examining it, and he says: 'When I touch it with my hand, the sale has become binding.' Then he has no option regarding it if he finds a defect in it. And in the prohibition of selling by mulamasah there is evidence for those who declare invalid the selling and buying of a blind person, because he only relies on and examines by touch what ought to be ascertained by sight and sound vision.

Al-munabadha is that he says: 'When I throw the garment to you, the sale has become binding.' This interpretation has come in the hadith. And Abu 'Abd Allah said: 'Al-munabadha is that he throws a stone and says: "When the stone falls, it is yours." This is analogous to the sale of the pebble (bay' al-hasah).'

As for al-ishtimal al-samma', it is that a man wraps himself in a single garment, placing the two ends of the garment on his left shoulder and letting down his right side. Thus its interpretation has come in the hadith.

As for al-ihtiba' (sitting on the haunches) in a single garment with nothing of his private parts exposed, it is that he sits on his buttocks, having raised his shins, while not wearing a waist-wrapper, then he wraps himself with a garment, joining its two ends and tying them over his knees. When he does this, a gap remains between him and the air through which his private parts become exposed."

(1) Its chain of transmission is sound. Ma'mar: he is Ibn Rashid, and 'Abd al-Razzaq: he is Ibn Hammam, and Al-Hasan ibn 'Ali: he is al-Khallal.
It was also recorded by al-Bukhari (2147) and al-Nasa'i (4515) via the chain of Ma'mar ibn Rashid, with this same chain of transmission. They limited themselves to mentioning the two types of garments along with the two types of sales, but without explaining the two types of garments.
It is also in "Musnad Ahmad" (11024), and "Sahih Ibn Hibban" (4976) and (5437).
And see what precedes it and what follows it.
