Ibn ’Abbas (RAA) narrated, ‘An elderly man is permitted to break his fast, but he must feed a poor person daily, and he does not have to make up for it.’ Related by Ad-Daraqutni and Al- hakim, who rendered it to be Sahih

وَعَنِ اِبْنِ عَبَّاسٍ ‏-رَضِيَ اَللَّهُ عَنْهُمَا‏- قَالَ: { رُخِّصَ لِلشَّيْخِ اَلْكَبِيرِ أَنْ يُفْطِرَ, وَيُطْعِمَ عَنْ كُلِّ يَوْمٍ مِسْكِينًا, وَلَا قَضَاءَ عَلَيْهِ } رَوَاهُ اَلدَّارَقُطْنِيُّ, وَالْحَاكِمُ, وَصَحَّحَاهُ [1]‏ .‏
