Highly emphasized to do Ablutions /wudhoo before going to sleep. A person sleeping in the state of having performed Wudhoo gets the reward of having done worship for the whole night.

The Prophet (saws) informed his daughter Fatima (sa) that before going to bed she should do 4 things (i-iv)

i) Recite Sura Ikhlass 3 times.This is like Reciting full Quran

ii) Recite Salwaat 10 times This will get intercession from Prophets

اَللَّهُمَّ صَلِّ عَلَىٰ مُحَمَّدٍ وَآلِ مُحَمَّدٍ

Allahumma Salle Ala Muhammadin Wa Aale Muhammad"
O Allah send blessings on Muhammad & his family

iii) Seek Forgiveness for all believers This is equal to making all believers happy

اللَّهُمَّ اغْفِرْ لِلْمُؤْمِنِينَ وَالْمُؤْمِنَاتِ

Allahuma maghfir le momineen wal moninaat "

O Allah Please forgive all the believing men & women

iv) Recite this which is equal to doing Haj & Umra

سُبْحَانَ اللهِ وَ الْحَمْدُ لِلهِ وَ لَا اِلٰهَ اِلَّا اللهُ وَ اللهُ اَكْبَر

"Subhaanallaahi wa’l hamdu lillaahi wa laa ilaaha illallaahu wallaahu Akbar ".

Glory be to God, and praise be to God; there is no god but Allah, and Allah is Greater

Recite 4 times 'Surah Al-Fatiha (is also known by several other names, such as Al-Hamd (The Praise), As-Salah (The Prayer), Umm al-Kitab (Mother of the Book), Umm al-Quran (Mother of the Quran), Sab'a min al-Mathani (Seven Repeated Ones, from Quran 15:87), and Ash-Shifa' (The Cure))' for sawab of giving 4000 dirhams sadqa & recite 'Astaghfirullah' 10 times to get sawab of resolving disputes between momins.

Recite this 3 times equals to reciting 1000 rakat. Imam Ali (as) reports from the Prophet (saws)

يفْعَلُ اللهُ مَا يَشَاءُ بِقُدْرَتِهِ وَيَحْكُمُ مَا يُرِيدُ بِعِزَّتِهِ

"Yafalollaho Mashao be qudrati wa yahkomo ma yurido be izzate"

He does what HE wills and rule what HE wills by HIS power
