On this there are discussions by the poskim with the suggestion that one would have to bensch again. (see: Taz Orach Chaim <span style="mso-spacerun: yes;">&nbsp;</span>693:2)</span></p>

When however Purim in Jerusalem (a walled city at the time of Yehoshua bin Nun and thus Purim is celebrated a day later) occurs on Shabbos, the seudas Purim is held on Sunday 16 Adar. On that day, one does not say &ldquo;al hanisim&rdquo; neither in the amidah nor in birchas hamazon. The question then asked is whether one should omit it even at the seudas Purim? On this, the Kaf Hachaim (688:48) writes that one should not say &ldquo;al hanisim&rdquo; in its usual place (between nodeh and ve&rsquo;al hakol) since this would be a hefsek, but adds that it is good to say it as an additional harachamon.<span style="mso-spacerun: yes;">&nbsp; </span></span></span></span></p> <p class="MsoNormal" style="line-height: normal; margin: 0in 0in 10pt;"><span style="mso-bidi-font-family: 'Times New Roman'; mso-ansi-language: EN-US;"><span style="font-size: small;"><span style="font-family: Times New Roman;">*************************************</span></span></span></p>

In a &ldquo;doubtful city&rdquo; namely one which celebrates Purim on both 14 and 15 Adar, because of a doubt on whether it was walled at the time of Yehoshua bin Nun, one has 2 days seudas Purim. (Mishnah Berurah 688:10) When Purim of a walled city falls on Shabbos, to keep all opinions one has a seudas Purim both on the Shabbos and on the Sunday. (Mishnah Berurah, Sha&rsquo;ar Hatziun 688:30) In such a case, a &ldquo;doubtful city&rdquo; will have a seudas Purim on the Friday, Shabbos and Sunday - namely 3 days seudas Purim.</span></span></span></p>
