Muwatta Malik, Book 2, Hadith 100 (USC-MSA) ⓘ

Yahya related to me from Malik from Abdullah ibn Abi Bakr from his paternal aunt from the daughter of Zayd ibn Thabit that she had heard that women used to ask for lamps in the middle of the night to check their purity. She would criticise them for this saying, "Women never used to do this," i.e. in the time of the companions. Malik was asked whether a woman whose period had finished could do tayammum to purify herself if she could not find waterand he said, "Yes, because she is like some one in a state of major ritual impurity, who, if he cannot find water, does tayammum."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرٍ، عَنْ عَمَّتِهِ، عَنِ ابْنَةِ زَيْدِ بْنِ ثَابِتٍ، أَنَّهُ بَلَغَهَا أَنَّ نِسَاءً، كُنَّ يَدْعُونَ بِالْمَصَابِيحِ مِنْ جَوْفِ اللَّيْلِ يَنْظُرْنَ إِلَى الطُّهْرِ فَكَانَتْ تَعِيبُ ذَلِكَ عَلَيْهِنَّ وَتَقُولُ مَا كَانَ النِّسَاءُ يَصْنَعْنَ هَذَا ‏.‏ وَسُئِلَ مَالِكٌ عَنِ الْحَائِضِ تَطْهُرُ فَلاَ تَجِدُ مَاءً هَلْ تَتَيَمَّمُ قَالَ نَعَمْ لِتَتَيَمَّمْ فَإِنَّ مِثْلَهَا مِثْلُ الْجُنُبِ إِذَا لَمْ يَجِدْ مَاءً تَيَمَّمَ ‏.‏
