ٱلْمُنَٰفِقُونَ وَٱلْمُنَٰفِقَٰتُ بَعْضُهُم مِّنۢ بَعْضٍۢ ۚ يَأْمُرُونَ بِٱلْمُنكَرِ وَيَنْهَوْنَ عَنِ ٱلْمَعْرُوفِ وَيَقْبِضُونَ أَيْدِيَهُمْ ۚ نَسُوا۟ ٱللَّهَ فَنَسِيَهُمْ ۗ إِنَّ ٱلْمُنَٰفِقِينَ هُمُ ٱلْفَٰسِقُونَ
The hypocrites, both men and women, proceed one from another. They enjoin the wrong, and they forbid the right, and they withhold their hands (from spending for the cause of Allah). They forget Allah, so He hath forgotten them. Lo! the hypocrites, they are the transgressors.

Funerals (Al-Janaa'iz)
Chapter: To make the hair of a (dead) woman fall at her back
Narrated Um 'Atiyya:
One of the daughters of the Prophet (ﷺ) expired and he came to us and said, "Wash her with Sidr (water) for odd number of times, i.e. three, five or more, if you think it necessary, and in the last, put camphor or (some camphor on her), and when you finish, notify me." So when we finished we informed him. He gave his waist-sheet to us (to shroud her). We entwined the hair (of the deceased girl) in three braids and made them fall at her back.
