وَيَٰقَوْمِ ٱعْمَلُوا۟ عَلَىٰ مَكَانَتِكُمْ إِنِّى عَٰمِلٌۭ ۖ سَوْفَ تَعْلَمُونَ مَن يَأْتِيهِ عَذَابٌۭ يُخْزِيهِ وَمَنْ هُوَ كَٰذِبٌۭ ۖ وَٱرْتَقِبُوٓا۟ إِنِّى مَعَكُمْ رَقِيبٌۭ
And, O my people! Act according to your power, lo! I (too) am acting. Ye will soon know on whom there cometh a doom that will abase him, and who it is that lieth. And watch! Lo! I am a watcher with you.
Surah Hud(11:93)
Sahih al-Bukhari
Oneness, Uniqueness of Allah (Tawheed)
Chapter: “And Allah is Ever All-Hearer, All-Seer.”
Narrated `Abdullah bin `Amr:
Abu Bakr As-Siddiq said to the Prophet (ﷺ) "O Allah's Messenger (ﷺ)! Teach me an invocation with which I may invoke Allah in my prayers." The Prophet (ﷺ) said, "Say: O Allah! I have wronged my soul very much (oppressed myself), and none forgives the sins but You; so please bestow Your Forgiveness upon me. No doubt, You are the Oft-Forgiving, Most Merciful."
Sahih al-Bukhari 7387, 7388
