Reference for Gittin 116:12

זו משנה ראשונה ב"ד של אחריהן אמרו הלוקח מן הסיקריקון נותן לבעלים רביע: אמר רב רביע בקרקע או רביע במעות ושמואל אמר רביע בקרקע שהן שליש במעות

this rule of sicaricon does not apply to it;<span class="x" onmousemove="('comment',' If he retains it for twelve months and then sells it to a Jew, the purchaser cannot be quit of the original owner by giving him merely a quarter, but he has to return him the whole, since he has never waived his title. [Trani reverses: The original owner has no claim to the field since he could have redeemed it, or in the case of anparuth recovered it at court (v. infra) and therefore it is to be assumed that he waived his right to the field. This interpretation is more in keeping with the reading, 'the rule of sicaricon does not apply', which varies but slightly from that of the Mishnah, whereas in Rashi's interpretation it is taken in a different sense.] ');">¹¹</span>
