Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 2|Chapter 37
وَ قَالَ أَبُو عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: «مَنْ لَمْ يَجِدِ اَلْحِنْطَةَ وَ اَلشَّعِيرَ أَجْزَأَ عَنْهُ اَلْقَمْحُ وَ اَلسُّلْتُ وَ اَلْعَلَسُ وَ اَلذُّرَةُ ».
Abu Abdullah عليه السلام said: "Whoever cannot find wheat or barley, it is sufficient for him to give in place of it wheat flour, spelt, emmer, or corn."
