وَ كَتَبَ مُحَمَّدُ بْنُ اَلْحَسَنِ اَلصَّفَّارُ إِلَى أَبِي مُحَمَّدٍ اَلْحَسَنِ بْنِ عَلِيٍّ عَلَيْهِ اَلسَّلاَمُ: فِي اِمْرَأَةٍ مَاتَ عَنْهَا زَوْجُهَا وَ هِيَ فِي عِدَّةٍ مِنْهُ وَ هِيَ مُحْتَاجَةٌ لاَ تَجِدُ مَنْ يُنْفِقُ عَلَيْهَا وَ هِيَ تَعْمَلُ لِلنَّاسِ هَلْ يَجُوزُ لَهَا أَنْ تَخْرُجَ وَ تَعْمَلَ وَ تَبِيتَ عَنْ مَنْزِلِهَا لِلْعَمَلِ وَ اَلْحَاجَةِ فِي عِدَّتِهَا قَالَ فَوَقَّعَ عَلَيْهِ اَلسَّلاَمُ "لاَ بَأْسَ بِذَلِكَ إِنْ شَاءَ اَللَّهُ".
Muhammad ibn al-Hasan al-Saffar wrote to Abu Muhammad al-Hasan ibn Ali (a.s) regarding a woman whose husband had passed away while she was still in her waiting period (iddah) and who was in need, with no one to provide for her, and she worked for people. He asked whether it was permissible for her to leave her house, work, and even stay away from her home overnight for work and necessity during her waiting period. Imam (a.s) responded: "There is no harm in that, God willing."
