Talmud for Shabbat 279:24

אמר רב חסדא האי כיתניתא

Rather said Abaye: It is a Rabbinical [prohibition], that one should not act as he does during the week. R. Johanan asked R. Jannai: May hiltith be dissolved in cold water? It is forbidden. replied he. But we learnt: HILTITH MUST NOT BE DISSOLVED IN WARM WATER, implying that it is permitted in cold water? If so,<span class="x" onmousemove="('comment',' That you do not accept me as a greater authority on the Mishnah than yourself. ');">¹⁹</span> what is the difference between you and me? Our Mishnah is [the opinion of] an individual. For it was taught: Hiltith may be dissolved neither in warm nor in cold water; R. Jose said: In warm water it is forbidden; in cold it is permitted. What is it made for? [As a remedy] for asthma.<span class="x" onmousemove="('comment',' Lit., 'heaviness of heart'. ');">²⁰</span> R. Aha b.Joseph suffered with asthma. He went to Mar 'Ukba, [who] advised him, 'Go and drink three [gold <i>denar</i>] weights of hiltith on three days.' He went and drank it on Thursday and Friday. The following morning he went and asked [about it] in the <i>Beth Hamidrash</i>.<span class="x" onmousemove="('comment',' To ask whether he might take it on Sabbath. ');">²¹</span> Said they to him, The school of R. Adda-others state, the school of Mar son of R. Adda recited: One may drink a <i>kab</i> or two <i>kabs</i> without fear.<span class="x" onmousemove="('comment',' Of transgression. ');">²²</span> About drinking, said he, I do not ask.<span class="x" onmousemove="('comment',' Lit., 'it was not in his hand'. ');">²³</span> My question is, What about dissolving it?<span class="x" onmousemove="('comment',' If the hiltith is dissolved before the Sabbath. ');">²⁴</span> R. Hiyya b. Abin observed to them: This case happened to me, and I went and consulted R. Adda b. Ahabah. but he could not inform me. [So] I went and asked R. Huna, and he answered me, Thus did Rab say: He may dissolve [it] in cold water and place it in the sun. Is this [only] according to him who permits [dissolving]? [No.] It is even according to him who forbids [it]: that is only if one had not drunk at all; but here, since he had drunk [it] on Thursday and Friday, if he would not drink it on the Sabbath he would be endangered. R. Aha b. Joseph was walking along, leaning<span class="x" onmousemove="('comment',' Lit., 'Supporting himself. ');">²⁵</span> on the shoulder of R. Nahman b. Isaac, his sister's son. When we reach R. Safra's house, lead me in, he requested.<span class="x" onmousemove="('comment',' He was an old man. ');">²⁶</span> When they arrived [there] he led him in. How about rubbing [the stiffness out of] linen [washing]?<span class="x" onmousemove="('comment',' When it is starched. The rubbing softens it and makes it whiter. ');">²⁷</span> asked he; is his intention to soften the linen, and it is permitted, or perhaps his intention is to make it whiter,<span class="x" onmousemove="('comment',' Lit., 'to beget whiteness'. ');">²⁸</span> which is forbidden? — His intention is to soften it, replied he, and it is permitted. When he went out he [R. Nahman] enquired, What did you ask him? I asked him, What about rubbing linen on the Sabbath, replied he, and he answered me, It is permitted. But let the Master inquire about a scarf?<span class="x" onmousemove="('comment',' Or, turban. ');">²⁹</span> I do not ask about a scarf, because I asked it of R. Huna and he decided it' for me. Then let the Master solve this from a scarf? — There it looks like making it whiter,<span class="x" onmousemove="('comment',' One is more particular about a scarf. ');">³⁰</span> but here it does not look like making it whiter. R. Hisda said: As for linen,
