There are five types: First: Routine Sunnah Prayers These are the ones regarding which Ibn ‘Umar (rahuma) said: “Ten rak‘ahs I remembered from the Messenger of Allah (SA): a. Two before dhuhr and two after it [1-4] b. Two after maghrib, at home [5-6] c. Two after ‘ishâ’, at home [7-8] d. Two before fajr. [9-10] Ḥafṣah (RAH) told me that the Messenger of Allah (SA) used to pray two rak‘ahs whenever fajr time came and the mu’adh-dhin called the adhân.” 301 These [two rak‘ahs before fajr] are the most stressed of all of them. 302 It is preferred to make them short, 303 and praying them at home is better.304 This applies to the two rak‘ahs of maghrib as well.
وَهِيَ عَلَى خَمْسَةِ أَضْرُبٍ: أحدها: السنن الرواتب وَهِيَ الَّتِيْ قَالَ ابْنُ عُمَرَ: " عَشْرُ رَكَعَاتٍ، حَفِظْتُهُنَّ مِنْ رَسُوْلِ اللهِ : أ) رَكْعَتَانِ قَبْلَ الظُّهْرِ، وَرَكْعَتَانِ بَعْدَهَا. ب) وَرَكْعَتَانِ بَعْدَ الْمَغْرِبِ فِيْ بَيْتِهِ. ت) وَرَكْعَتَانِ بَعْدَ الْعِشَاءِ فِيْ بَيْتِهِ. ث) وَرَكْعَتَانِ قَبْلَ الْفَجْرِ. وحَدَّثَتْنِيْ حَفْصَةُ أَنْ رَسُوْلَ اللهِ كَانَ إِذاَ طَلَعَ الْفَجْرُ وَأَذَّنَ الْمُؤَذِّنُ، صَلَّى رَكْعَتَيْنِ." وَهُمَا آكَدُهَا، وَيَسْتَحَبُّ تَخْفِيْفُهُمَا، وَفِعْلُهُمَا فِي الْبَيْتِ أَفْضَلُ وَكَذٰلِكَ رَكْعَتَا الْمَغْرِبِ
