B"H

This Responsum is attributed to Rabbi Yehoshua' Ha-Nagid, one of the descendants of Maimonides, of blessed memory, concerning those questions asked him by the people of the city Aden, and who concluded the following:

"Wheat grains which have been prepared in this manner, they constitute what we call unleavened bread kept [in preparation fitting for the Passover], and it is [only] this which is worthy of making a blessing over, [Blessed art thou, O Lo-rd our G-d, etc. who hast sanctified us, etc. and commanded us] to eat unleavened bread. And let him eat with it the afikoman, for anything taken which is not after the aforescribed manner is called unleavened bread that has not been [duly] kept. But if he has not found unleavened bread kept in watch [for the Passover], he is permitted to bless over unleavened bread that has not been [duly] kept, and to eat of it during all [the days of] the Passover, since it was not known unto us whether or not water had actually fallen upon that wheat, [and] since, [moreover], there is a principle with us [that states] we do not assume an ordinary thing to be under a prohibition. Nevertheless, [a person] must make every effort [to obtain] a grain crop used in making the unleavened bread that has been properly watched over, as it is written: And thou shalt keep the unleavened bread (Shemos 12:17), meaning, keep it for the sake of unleavened bread."
