Khushu‘ (proper focus and humility) form the essence of prayer; by means of khushu‘ the worshipper will be calm and unhurried in his prayer, and will turn more wholeheartedly to Allah (may He be glorified). The Prophet (blessings and peace of Allah be upon him) taught the Muslims the etiquette of prayer and what is most important when praying, so that their prayer might be perfected. In this hadith, Anas ibn Malik (may Allah be pleased with him) narrates that the Prophet (blessings and peace of Allah be upon him) led them in prayer, then he ascended the minbar and spoke regarding the prayer and bowing, meaning that he exhorted them with regard to the prayer and bowing. He singled out bowing for mention, even though it is included in the prayer, because he wanted to pay extra attention to it, either because it is the greatest of the essential parts of the prayer, based on the fact that if a latecomer to a congregational prayer catches up with bowing, he has caught up with that entire rak‘ah, or because he knew that they were falling short in bowing, so he mentioned it in order to highlight their shortcomings in it. Then he said: “Indeed I can see you behind me as I see you [now].” This was one of his miracles and unique characteristics, and one of the proofs of his prophethood. What is meant is that Allah (may He be exalted) had created in him the ability to know what was happening behind him, and his seeing meant knowing in a true sense what was happening, by extraordinary means. The Prophet (blessings and peace of Allah be upon him) was granted many extraordinary feats and events in addition to this, and nothing in that is contrary to rational thinking or religious texts, rather the religious texts speak of such miracles and extraordinary events, so we must believe in them. It may be that the Prophet (blessings and peace of Allah be upon him) saw them through what was revealed to him about their actions and how they performed the prayer, because seeing may mean knowing and believing. What he meant when he said that was: Focus properly in the prayer, with humility, and bow and do the essential parts thereof properly, as if I am watching you and directing you to do it correctly, for I see your actions in prayer behind me when I am standing and leading you in prayer and you are behind me, just as I see you when I am looking at you in front of me. This hadith urges us to offer the prayer in the manner enjoined by Allah (may He be glorified and exalted). It is also one of the proofs of the prophethood of the Prophet (blessings and peace of Allah be upon him)..
