I like to add the following explanation: ٢_١٥٧ أُو۟لَٰٓئِكَ عَلَيْهِمْ صَلَوَٰتٌۭ مِّن رَّبِّهِمْ وَرَحْمَةٌۭ ۖ وَأُو۟لَٰٓئِكَ هُمُ ٱلْمُهْتَدُونَ Those are they on whom are blessings and mercy from their Lord, and those are the followers of the right course. Blessing is sent to the prophet (صلى الله عليه وآله وسلم) and his progeny (عليه السلام) as mentioned below: اِنَّ اللَّهَ وَمَلآَئِكَتَهُ يُصَلُّونَ عَلَي النَّبِيّ‌ِ يَآ أَيُّهَا الَّذِينَ ءَامَنُوا صَلُّوا عَلَيْهِ وَس
