If an Israelite was too poor to offer a lamb or a goat as a sacrifice, he could offer instead two turtledoves or two pigeons. But what if an Israelite was so poor that he could not even afford two pigeons?
وَإِنْ كَانَ أَفْقَرَ مِنْ أَنْ يُقَدِّمَ فَرْخَيْ يَمَامٍ ،‏ يُسْمَحُ لَهُ أَنْ يُحْضِرَ ٱلْقَلِيلَ مِنَ ٱلدَّقِيقِ .‏
