وَيَٰقَوْمِ ٱعْمَلُوا۟ عَلَىٰ مَكَانَتِكُمْ إِنِّى عَٰمِلٌۭ ۖ سَوْفَ تَعْلَمُونَ مَن يَأْتِيهِ عَذَابٌۭ يُخْزِيهِ وَمَنْ هُوَ كَٰذِبٌۭ ۖ وَٱرْتَقِبُوٓا۟ إِنِّى مَعَكُمْ رَقِيبٌۭ
And, O my people! Act according to your power, lo! I (too) am acting. Ye will soon know on whom there cometh a doom that will abase him, and who it is that lieth. And watch! Lo! I am a watcher with you.

Chapter: The laws inferred from certain evidences; and the meaning of an evidence
Narrated `Aisha:
A woman asked the Prophet (Hadith 456). Narrated `Aisha: A woman asked the Prophet (ﷺ) about the periods: How to take a bath after the periods. He said, "Take a perfumed piece of cloth and clean yourself with it." She said,' "How shall I clean myself with it, O Allah's Messenger (ﷺ)?" The Prophet (ﷺ) said, "Clean yourself" She said again, "How shall I clean myself, O Allah's Messenger (ﷺ)?" The Prophet (ﷺ) said, "Clean yourself with it." Then I knew what Allah's Messenger (ﷺ) meant. So I pulled her aside and explained it to her.
