Allah encompasses and watches all of Man's Activity

Allah the Exalted affirms His absolute dominance over mankind, being their Creator and the Knower of everything about them. Allah the Exalted has complete knowledge of all thoughts that cross the mind of man, be they good or evil. In the Sahih, the Messenger of Allah ﷺ said,

«إِنَّ اللهَ تَعَالَى تَجَاوَزَ لِأُمَّتِي مَا حَدَّثَتْ بِهِ أَنْفُسَهَا مَا لَمْ تَقُلْ أَوْ تَعْمَل»

Every Utterance of Man is recorded

مَّا يَلْفِظُ مِن قَوْلٍ إِلَّا لَدَيْهِ رَ‌قِيبٌ عَتِيدٌ (Not a single word is uttered by one, but there is a watcher near him, ready [ to record ]...50:18) In other words, there is always a supervising angel [ the scribe ] whose responsibility is to record any word that the human utters or speaks. Sayyidna Hasan Basri and Qatadah رحمۃ اللہ علیہما said that this angel records every single word - whether or not it is sinful or reward-able. Ibn ` Abbas ؓ said that only those utterances are recorded that are sinful or rewardable. Ibn Kathir, having quoted both these views, preferred the first view on the basis of the general words of the verse that every utterance is recorded. According to another narration of Sayyidna Abu Talhah ؓ from Ibn ` Abbas ؓ both the views can be accommodated. This narration states that in the first instance every utterance is recorded, whether or not it is sinful or rewardable. Once a week on Thursdays, the angels review the recorded utterances and retain only those that are sinful or rewardable, good or bad; the rest are discounted. Thus the Qur'an says: يَمْحُو اللَّـهُ مَا يَشَاءُ وَيُثْبِتُ "Allah wipes off what He wills and affirms (what He wills). And with Him is the Mother Book." (Ar-Ra` d 39)
