Ayat 42. Say: "Who can guard and protect you in the night or in the day from the (punishment of the) Most Beneficent (Allah)?" Nay, but they turn away from the remembrance of their Lord.
Ayat 43. Or have they âliha (gods) who can guard them from Us? They have no power to help themselves, nor can they be protected from Us (i.e. from Our Torment).
[Tafseer] Say: "Who can keep you safe by night and by day from (the Wrath of) (Allah) Most Gracious?" Yet they turn away from the mention of their Lord. 'Allah is most Gracious: if, in spite of His great mercy, you are so rebellious and depraved as to incur His Wrath, who is there who can save you? His Wrath can descend on you at any rime, by night or by day.' Or have they gods that can guard them from Us? They have no power to aid themselves, nor can they be defended from Us. Ashaba: to join as a companion: with 'an or min it has also the meaning of to defend or remove from someone. The full signification is best understood if paraphrased: 'they are not fit to be mentioned in the same breath with Us, nor can they be defended from Us.'
Hazrat Aishah (May Allah be pleased with her) reported: The Messenger of Allah [SAWW](PBUH) used to supplicate (in these words): "Allahumma inni audhu bika min sharri ma `amiltu, wa min sharri ma lam a`mal (O Allah! I seek refuge in You from the evil of that which I have done and the evil of that which I have not done).''
[Muslim Book 35, Chapter 17, Hadith # 6558]Lesson : as mentioned above in Surah Al-Anbiya' Ayat 42."Who can guard and protect you in the night or in the day" This prayer is also very comprehensive. Sometimes a person does a virtuous deed but it is tainted with slight hypocrisy or pride. It is an element which destroys even the most virtuous deeds. It is this mischief against which Allah's Protection has been sought through this prayer.
