عَنْ مُطَرِّفِ بْنِ عَبْدِ اللَّهِ بْنِ الشِّخِّيرِ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ أَنَّهُ سَمِعَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَسُئِلَ عَنْ رَجُلٍ يَصُومُ الدَّهْرَ، قَالَ: ((لَا صَامَ وَلَا أَفْطَرَ))
It is narrated from Sayyiduna Abdullah bin Shukhair (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) was asked about the person who always fasts. He (peace and blessings be upon him) said: Neither has he fasted nor has he abandoned it.
