[Machine] Aisha, the mother of the believers, said to me, "Can't any one of you, after being purified from menstruation, find some piece of cloth and use it as a wick? If you do not find a wick, then use some cotton. If you do not find cotton, then use some flax. If you do not find flax, then use some salt."  

الدارمي:١٢٠١أَخْبَرَنَا مُحَمَّدُ بْنُ الْمِنْهَالِ حَدَّثَتْنِي حَبِيبَةُ بِنْتُ حَمَّادٍ حَدَّثَتْنِي عَمْرَةُ بِنْتُ حبَّانَ السَّهْمِيَّةُ قَالَتْ

قَالَتْ لِي عَائِشَةُ أُمُّ الْمُؤْمِنِينَ «أَمَا تَسْتَطِيعُ إِحْدَاكُنَّ إِذَا تطَهُرَتْ مِنْ حَيْضِهَا أَنْ تتدَخِّنَ بشَيْء مِنْ قُسْطٍ فَإِنْ لَمْ تَجِدْ فَشَيْئًا مِنْ آسٍ فَإِنْ لَمْ تَجِدْ فَشَيْئًا مِنْ نَوًى فَإِنْ لَمْ تَجِدْ فَشَيْئًا مِنْ مِلْحٍ»
