As-Salaam alaikum,
The Holy Prophet, Sallallahu alaihi Wasallam, once advised his beloved wife, Sayyada A'isha, may Allah be pleased with her, saying:-

"O A'isha, before you sleep you should perform 4 deeds:
(1) You should complete the recital of the Holy Qur'an
(2) You should make sure that the Prophets intercede for you on the Day of Judgement.
(3) You should make sure that the entire Muslim Ummah is happy, and
(4) You should perform the Hajj and Umrah."

She asked him as to how it was possible to complete all these deeds before going to sleep. The Prophet, Sallallahu alaihi Wasallam, smiled and replied:--

"O A'isha, when you read Surah Ikhlas 3 times, it is as if you have read the entire Qur'an.
When you read the prayer for blessings and peace upon me and all the preceding Prophets
[Salaat ala Nabiy wa ala Nabi'eena wal Mursaleen], then we will certainly intercede for you
on the Day of Judgement.
When you make Du'a for all the Muslims, they will be happy with you.
When you read the following: SUBHANALLAHI, WAL-HAMDULILLAHI, WALA ILAHA ILLALLAHU
WALLAHU AKBAR, then it is as if you have performed Hajj and Umrah."
