Se’if 1א׳

דָּגָן שֶׁנִּטְבַּע בַּנָּהָר אוֹ שֶׁנָּפַל עָלָיו מַיִם, כְּשֵׁם שֶׁאָסוּר לְאָכְלוֹ כָּךְ אָסוּר לְקַיְּמוֹ, אֶלָּא מוֹכְרוֹ לְיִשְׂרָאֵל וּמוֹדִיעוֹ, כְּדֵי שֶׁיֹּאכְלֶנּוּ קֹדֶם הַפֶּסַח; וְאִם מְכָרוֹ לְעַכּוּ"ם קֹדֶם פֶּסַח, מוֹכֵר מְעַט לְכָל אֶחָד וְאֶחָד כְּדֵי שֶׁיִּכְלֶה קֹדֶם הַפֶּסַח, שֶׁמָּא יַחֲזֹר הָאֵינוֹ יְהוּדִי וְיִמְכְּרֶנּוּ לְיִשְׂרָאֵל.

Laws of wheat upon which water fell, and a cooked dish in which a wheat kernel was found. Contains 16 sections Grain that was submerged in a river or upon which water fell — just as it is forbidden to eat it, so too it is forbidden to keep it. Rather one sells it to a Jew and informs him so that he eats it before Passover. If he sold it to a non-Jew before Passover, he sells a little to each one so that it will be consumed before Passover, lest the non-Jew resell it to a Jew.

Se’if 2ב׳

הַגָּה: וְלָכֵן יֵשׁ לִזָּהֵר שֶׁלֹּא יָבוֹאוּ מַיִם אוֹ גְּשָׁמִים מְזַלְּפִים עַל הַחִטִּים, כִּי אָז אֲפִלּוּ לֹא נִתְבַּקְּעוּ, אֲסוּרוֹת. דָּגָן זֶה שֶׁנִּטְבַּע בַּנָּהָר אוֹ שֶׁנָּפְלוּ עָלָיו מַיִם, אַף עַל פִּי שֶׁלֹּא נִתְבַּקַּע, אָסוּר דְּכֵיוָן דְּמִינַח נַיְחֵי אָתֵי לִידֵי חִמּוּץ. הַגָּה: וְדָגָן שֶׁהָיָה מֻנָּח בָּעֲלִיָּה וְיָרְדוּ גְּשָׁמִים דֶּרֶךְ הַגַּג בִּקְצָת הַמְּקוֹמוֹת וְנִתְלַחְלְחוּ, אוֹתָן שֶׁנִּתְלַחְלְחוּ אֲסוּרוֹת, אֲבָל שְׁאָר מְקוֹמוֹת מֻתָּר לְהַשְׁהוֹתָן מִכֹּחַ סְפֵק סְפֵיקָא, שֶׁמָּא לֹא יָרְדוּ עֲלֵיהֶם גְּשָׁמִים, וְאִם תִּמְצֵי לוֹמַר יָרְדוּ, שֶׁמָּא לֹא נִתְחַמְּצוּ; אֲבָל לְאָכְלָן בְּפֶסַח אָסוּר, וְלֹא מְהָנֵי סְפֵק סְפֵיקָא (אָגוּר וְכָל בּוֹ).

Such grain that was submerged in a river or upon which water fell — even if it did not split open — is forbidden, since when it rests undisturbed it comes to leavening. Rema: Therefore one should be careful that water or drizzling rain not come upon wheat, for then even if the kernels did not split open they are forbidden. Grain that was stored in an attic and rain came through the roof in some places and moistened it — those that became moist are forbidden, but the rest may be kept on account of a double doubt: perhaps the rain did not fall on them, and even if it did, perhaps they did not become leavened. But to eat them on Passover is forbidden, and a double doubt does not help for that.

Se’if 3ג׳

חִטִּים שֶׁבָּאוּ בַּסְפִינָה, אִם הֵם יְבֵשׁוֹת וְקָשׁוֹת וְלֹא נִשְׁתַּנָּה מַרְאֵיהֶן, אַחְזוּקֵי אִסוּרָא לֹא מְחַזְּקִינָן.

Wheat that came by ship — if it is dry and hard and its appearance has not changed, we do not presume it to be forbidden.
