disc▪ Jeffery1938: »The exegetes derive the word from sannama ‘to raise’, form II of sanima ‘to be high’, and the fountain is said to be called tasnīm because the water is carried from it to the highest apartment of the Pavilion, cf. Zam. on the passage, and Ṭab. quoting Muǧāhid and Al-Kalbī; also LA, xv, 199. It is obvious, however, that this is merely an attempt to explain a word that was strange to the exegetes, and which lent itself to explanation as a form tafʕīl from sanima. There is no occurrence of the word earlier than the Qurʔān, and apparently nothing in the literature of the surrounding peoples from which we can derive it, so Nöldeke is doubtless right when in his Sketches, 38, he takes the word to be an invention of Muḥammad himself.«
