Abu Mijlas states, “On one occasion, Hazrat Ammar bin Yassir (ra) offered the prayer but kept it short. Someone asked him the reason for doing so. He responded, ‘I did not deviate even to the slightest degree from the manner in which the Holy Prophetsa offered his prayer.’”
(Musnad Ahmad bin Hanbal, Vol. 6, p. 262, Ammar bin Yassir, Hadith 18514, Aalam-ul-Kutub, Beirut, 1998)
This narration is further explained by another narration from Abu Mijlas. He states, “Once Hazrat Ammar bin Yassir (ra) led us in a very short prayer which left the people astonished. Hazrat Ammar (ra) stated: ‘Did I not complete the ruku‘ and sujood [bowing down and prostrating in prayer]?’ They responded: ‘Yes, certainly you did.’ Hazrat Ammar (ra) responded: ‘I offered a prayer of the Holy Prophet (sa) in this Salat which is as follows:
اَللّٰهُمَّ بِعِلْمِكَ الْغَيْبَ وَقُدْرَتِكَ عَلَي الْخَلْقِ أَحْيِنِيْ مَا عَلِمْتَ الْحَيَاةَ خَيْرًا لِي وَتَوَفَّنِيْ اِذَا كَانَتِ الْوَفَاةُخَيْرًا لِيْ۔ اَسْأَلُكَ خَشْيَتَكَ فِي الْغَيْبِ وَالشَّهَادَةِ وَكَلِمَةَ الْحَقِّ فِي الْغَضَبِ وَالرِّضَا وَالْقَصْدَ فِيالْفَقْرِوَالْغِنٰي وَلَذَّة النَّظَرِ اِلٰي وَجْهِكَ وَالشَّوْقَ اِلٰي لِقَائِكَ وَاَعُوْذُبِكَ مِنْ ضَرَّاءَ مَضَرَّةٍ وَمِنْ فِتْنَةٍمُضِلَّةٍ۔ اَللّٰهُمَّ زَيِّنَّا بِزِيْنَةِ الْاِيْمَانِ وَاجْعَلْنَا هُدَاةً مَهْدِيِّيْنَ
“O Allah, You are aware of the knowledge of the unseen and Your power encompasses all of creation. I implore You to keep me alive only to the time you think my life is good for me and give me death when it is better for me. O Allah! I seek Your protection from the unseen and that what is visible, and I beg You to grant me the strength to speak the truth when in a state of anger and delight. I beseech You to grant me the ability to adopt the middle way during times of difficulty as well as abundance. I beg You to grant me the delightful sight to witness Your holy countenance and the eagerness and desire to meet You. I seek Your protection from any affliction and mischief that can lead one astray. O Allah! Adorn us with the beauty of faith and make us those from whom people find guidance.”

It is also mentioned in a narration that Hazrat Ammar bin Yassir (ra) would recite Surah Ya-Sin at the pulpit on Fridays.
