فَٱعْلَمْ أَنَّهُۥ لَآ إِلَـٰهَ إِلَّا ٱللَّهُ وَٱسْتَغْفِرْ لِذَنۢبِكَ وَلِلْمُؤْمِنِينَ وَٱلْمُؤْمِنَـٰتِ ۗ وَٱللَّهُ يَعْلَمُ مُتَقَلَّبَكُمْ وَمَثْوَىٰكُمْ Qur’an Muhammad (47:19)Fa i AAlam annahu l a il a ha ill a All a hu wa i staghfir li th anbika walilmumineena wa a lmumin a ti wa A ll a hu yaAAlamu mutaqallabakum wamathw a kum
I.e., "He knows all that you do and all that you fail to do".
Like other prophets, Muḥammad (ﷺ) was infallible of sin. The verse here refers to misjudgments, such as the example given in 80:1-10. If the Prophet (ﷺ) himself is urged to seek forgiveness, then the believers are even more in need of praying for Allah’s forgiveness.
Cf. xl. 55, and n. 4428.
The time and manner of our conducting ourselves at home and when we move about on our business are all material to the judgment of our conduct, and for every nuance in our moral and spiritual progress, we must seek Allah's help and guidance.
