Allaah Kareem says in the Holy Qur'aan, in the 25th Soorah, al-Furqaan:
Verse 64
Those who pass the night [in adoration] for their Lord in prostration and standing
Allaah Almighty Averts Punishment Of The Disobedient Because Of Auliya Allaah
After praising Allaah Kareem (Hamd) and blessing His beloved Holy Prophet (Salawaat), I recited a verse of the Holy Qur’aan. In this verse Allaah Kareem has mentioned an attribute of His beloved servants. He says that His accepted and beloved servants, their prominence is this that they spend nights in prostration [sajda]before their Creator. He states:
[They] pass the night [in adoration] for their Lord How do they spend it?
in prostration and standing [qiyaam]
The rest of the world is asleep and dreaming but the servants of the Merciful Allaah Kareem, His accepted servants, spend their nights, for Allaah Kareem, soaked in His love, praying salaah, standing (qiyaam), bowing(ruuku) and prostrating (sajdaah).
The reality is this that because of these worshipful and pondering or reflecting (fikr) servants this world retains stability and we are saved from the punishment of Allaah Kareem.Excerpt lecture translation of Hazrat Maulana Shafee Okarvi [Rahmatul Laahi Alaieh]
