Allah's special favor to the Prophet Muhammad

لِّيَغْفِرَ لَكَ ٱللَّهُ مَا تَقَدَّمَ مِن ذَنۢبِكَ وَمَا تَأَخَّرَ وَيُتِمَّ نِعْمَتَهُۥ عَلَيْكَ وَيَهْدِيَكَ صِرَٰطًا مُّسْتَقِيمًا

That Allāh may forgive for you what preceded of your sin [i.e., errors] and what will follow and complete His favor upon you and guide you to a straight path
