What is the meaning of the Prophet’s words, “I can see you behind my back”?
Question

                Hadith from Sahih Bukhari

Narrated Abu Huraira: Allahs Apostle said, "Do you consider or see that my face is towards the Qibla? By Allah, neither your submissiveness nor your bowing is hidden from me, surely I see you from my back."

Does this mean that Prophet could have seen at things behind him as well? Please clarify.
Praise be to Allah.
    
    One of the miracles of which the Prophet (blessings and peace of Allah be 
    upon him) told his Companions is that he could see them behind his back, as 
    he could see them in front of him. 

    
    Al-Bukhaari (741) and Muslim (424) narrated from Abu Hurayrah (may Allah be 
    pleased with him) that the Messenger of Allah (blessings and peace of Allah 
    be upon him) said: “Do you think that I face the qiblah (and do not know 
    what you are doing)? By Allah, your bowing and prostrating are not hidden 
    from me; I can see you behind my back.”

    
     Ahmad (9504) narrated that Abu Hurayrah (may Allah be pleased with him) 
    said: The Messenger of Allah (blessings and peace of Allah be upon him) led 
    us in praying Zuhr, and in the last row there was a man who prayed badly. 
    When he said the salaam, the Messenger of Allah (blessings and peace of 
    Allah be upon him) called him and said: “O So and so, do you not fear Allah? 
    Do you not see how you pray. You think that you could hide from me some of 
    what you do, but by Allah I can see behind me as well as I can see in front 
    of me.”

    Mishkaat al-Masaabeeh (no. 811) 

    
    The word seeing mentioned in the hadeeths is to be understood as it appears 
    to mean, i.e., that he could see them visually. This is indicated by the 
    report narrated by Muslim (423) from the hadeeth of Abu Hurayrah (may Allah 
    be pleased with him) who said: The Messenger of Allah (blessings and peace 
    of Allah be upon him) prayed one day, then he finished and said: “O So and 
    so, why don’t you pray well? Why doesn’t the worshipper look at how he is 
    praying when he prays? He is only praying for himself. By Allah, I can see 
    behind me as well as I can see in front of me.” 

    
    An-Nawawi (may Allah have mercy on him) said, commenting on this hadeeth: 
    The scholars said: What this means is that Allah, may He be exalted, created 
    for the Prophet (blessings and peace of Allah be upon him) the ability in 
    the back of his head to see what was behind him, and he (blessings and peace 
    of Allah be upon him) was granted more extraordinary abilities than this. 
    This is not contrary to reason or textual evidence; rather the texts confirm 
    this, so we must believe in it. Al-Qaadi said: Ahmad ibn Hanbal (may Allah 
    have mercy on him) and the majority of the scholars said that this seeing 
    was in a literal and real sense.

    Al-Haafiz Ibn Hajar (may Allah have mercy on him) said: There was a 
    difference of scholarly opinion as to the meaning of this. It was said that 
    what was meant is knowledge, either by means of Revelation so that he knew 
    thereby how people really performed the prayer, or by means of inspiration. 
    But this is subject to further discussion, because if what is meant is mere 
    knowledge, he would not have specified by saying “behind my back.” And it 
    was suggested that what is meant is that he could see whoever was on his 
    right and on his left, of those on whom his gaze fell if he turned slightly 
    sometimes, and he described those who were standing there as being behind 
    his back. But this appears to be stretching the meaning and it is turning 
    away from the apparent meaning when there is no need to do so. 

    
    The correct view is that it is to be interpreted as it appears to mean, and 
    that this “seeing” was in a real and literal sense that was unique to the 
    Prophet (blessings and peace of Allah be upon him) and was an extraordinary 
    feat. Based on that, the author narrated this hadeeth under the heading of 
    the signs of Prophethood; it was also narrated under a similar heading from 
    Imam Ahmad and others.

    Does this miracle include times of prayer and other situations? The text 
    refers to prayer; as for other situations, there is no text that speaks of 
    them. According to some scholars that is possible, but according to others 
    it applied only to the case of prayer. 

    
    Al-Haafiz Ibn Hajar (may Allah have mercy on him) said: The apparent meaning 
    of the hadeeth is that this was something limited to the case of prayer, but 
    it may be that this happened in all situations. That was also narrated from 
    Mujaahid.

    Mullah ‘Ali al-Qaari said: The words “I can see you behind my back” do not 
    necessarily mean that this occurred all the time, because it is contrary to 
    the report which says “I do not know what is behind my wall.” Hence this was 
    unique to the case of prayer and his knowledge about the worshippers behind 
    him. And Allah knows best.

    Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) said: He could see them 
    behind his back, and this is something that was unique to the Prophet 
    (blessings and peace of Allah be upon him): in this particular situation 
    (i.e., prayer) he could see the people behind his back. But in other 
    situations, he could not see anything behind his back.
