وَ رُوِيَ عَنِ اَلْحُسَيْنِ بْنِ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ اَلثَّانِي عَلَيْهِ اَلسَّلاَمُ: أَنَّهُ سُئِلَ مَا فَرْقُ مَا بَيْنَ اَلْفُسْطَاطِ وَ بَيْنَ ظِلِّ اَلْمَحْمِلِ قَالَ «لاَ يَنْبَغِي أَنْ يُسْتَظَلَّ فِي اَلْمَحْمِلِ وَ اَلْفَرْقُ بَيْنَهُمَا أَنَّ اَلْمَرْأَةَ تَطْمَثُ فِي شَهْرِ رَمَضَانَ فَتَقْضِي اَلصِّيَامَ وَ لاَ تَقْضِي اَلصَّلاَةَ» قَالَ صَدَقْتَ جُعِلْتُ فِدَاكَ.
It was narrated from Al-Husayn ibn Muslim, who said: I asked Abu Ja'far the Second (a.s): "What is the difference between a tent (fusṭāṭ) and the shade of a litter (maḥmil)?" Imam (a.s) said: "One should not seek shade in the maḥmil. The difference between them is like the case of a woman who menstruates during Month of Ramadan; she makes up the fasts but does not make up the prayers." I replied: "You have spoken the truth, may I be your ransom."
