They are merely words of good cheer  R. Ashi said to him: Why so? [Is it] because the buyer should have stipulated, whilst here the vendor did so, and therefore you maintain that they were merely words of good cheer? But [what of] the Baraitha wherein it is taught: [If the purchaser says,] 'When you have money, I will resell it to you,' that is permitted? Now, surely [there too] though the vendor should have made this stipulation,  the vendor did not stipulate but the buyer; and yet when we asked,  What is the difference between the first clause and the second, Raba answered: In the second clause he [the purchaser] stipulates that it [the resale] should be voluntary, thus implying that if he does not stipulate that it should be voluntary [the transaction would be forbidden], and we do not assume that [his offer] was merely words of good cheer!  — He replied: What was said was that it is accounted as though he had stipulated that it [the re-sale] should be voluntary. A certain sick man  wrote a get  for his wife.  He then groaned and sighed, whereupon she [his wife] said to him, 'Why do you sigh? should you recover, I am yours.' Said R. Zebid: These were mere words of consolation. R. Aha of Difti asked Rabina: And what if they were not mere words of consolation? Does it lie within her power to insert a condition in the get? Surely it rests only with him to give the get on a condition! — I might think, he himself meant to give the get in accordance with her desires.  Hence he teaches otherwise. IF HE LENT MONEY ON A FIELD. R. Huna said: [If he stipulated thus] when lending the money, it becomes completely his;  if after, he acquires [of the field] only in proportion to the money owing. R. Nahman said: [Even if the stipulation was made] after lending the money, it becomes completely his. Now, R. Nahman gave a practical decision at the Resh Galutha's [court]  in accordance with his ruling. Rab Judah [however] tore up the document [embodying his decision]. Said the Resh Galutha to him: Rab Judah has torn up your document. He replied: Did then a child tear it up? It was a great man who tore it up. He must have seen some reason therein [to invalidate it], and hence tore it up. Others say: He [R. Nahman] replied: A child has torn it up, for in civil law everyone is a child compared to me. Subsequently R. Nahman ruled: Even [if the stipulation was made] when the money was being handed over, he [the creditor] acquires no rights therein at all. Raba objected to R. Nahman: IF YOU DO NOT REPAY ME WITHIN THREE YEARS, IT [THE FIELD] IS MINE,' — IT BECOMES HIS! — He replied: I used to rule that an asmakta  is binding, but Minyomi ruled that it is not.  But [then] according to Minyomi, is not our Mishnah difficult? — If you wish, I can answer that the Mishnah agrees with R. Jose, who ruled that an asmakta is legally valid;
