أَفَلَمْ يَرَوْا۟ إِلَىٰ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُم مِّنَ ٱلسَّمَآءِ وَٱلْأَرْضِ ۚ إِن نَّشَأْ نَخْسِفْ بِهِمُ ٱلْأَرْضَ أَوْ نُسْقِطْ عَلَيْهِمْ كِسَفًۭا مِّنَ ٱلسَّمَآءِ ۚ إِنَّ فِى ذَٰلِكَ لَءَايَةًۭ لِّكُلِّ عَبْدٍۢ مُّنِيبٍۢ
Have they not observed what is before them and what is behind them of the sky and the earth? If We will, We can make the earth swallow them, or cause obliteration from the sky to fall on them. Lo! herein surely is a portent for every slave who turneth (to Allah) repentant.

Menstrual Periods
Chapter: To take a bath after finishing from the menses
Narrated `Aisha:
An Ansari woman asked the Prophet (ﷺ) how to take a bath after finishing from the menses. He replied, "Take a piece a cloth perfumed with musk and clean the private parts with it thrice." The Prophet (ﷺ) felt shy and turned his face. So I pulled her to me and told her what the Prophet (ﷺ) meant.
