وَإِذْ قَالَ عِيسَى ٱبْنُ مَرْيَمَ يَٰبَنِىٓ إِسْرَٰٓءِيلَ إِنِّى رَسُولُ ٱللَّهِ إِلَيْكُم مُّصَدِّقًۭا لِّمَا بَيْنَ يَدَىَّ مِنَ ٱلتَّوْرَىٰةِ وَمُبَشِّرًۢا بِرَسُولٍۢ يَأْتِى مِنۢ بَعْدِى ٱسْمُهُۥٓ أَحْمَدُ ۖ فَلَمَّا جَآءَهُم بِٱلْبَيِّنَٰتِ قَالُوا۟ هَٰذَا سِحْرٌۭ مُّبِينٌۭ
And when Jesus son of Mary said: O Children of Israel! Lo! I am the messenger of Allah unto you, confirming that which was (revealed) before me in the Torah, and bringing good tidings of a messenger who cometh after me, whose name is the Praised One. Yet when he hath come unto them with clear proofs, they say: This is mere magic.

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.
