قُلْتُ لِأَبِي عَبْدِ اللَّهِ أَوْ لِأَبِي الْحَسَنِ ع الرَّجُلُ يَتَعَمَّدُ الشَّهْرَ فِي الْأَيَّامِ الْقِصَارِ يَصُومُهُ لِسَنَةٍ قَالَ لَا بَأْسَ[1].
“I once asked abu ‘ Abd Allah (a.s.), about a man who purposely postpones fasting for the times when days of the year are shorter. He (the Imam) said, ‘It is not harmful.’”
