Hadhrat Anas (May Allah be well pleased with him) says: "The Holy Prophet (Sallallahu alaihi wa sallam) went to the mountain of Uhud. Hadhrat Abu Bakr As Siddiq, Hadhrat Umar al Farooq and Hadhrat Usman Al Ghani went along with Him. When they climbed the mountain, the mountain started swaying out of happiness. The Holy Prophet (Sallallahu alaihi wa sallam) tapped it with His feet and said, O Uhud stay still; a Prophet, a Siddiq and two martyrs are standing on you." (Sahih Bukhari, Vol 1, Pg No: 519)
Whenever the Holy Prophet (Sallallahu alaihi wa sallam) walked, earth would be rolled up for Him.(Jame’ Tirmidhi, Vol 2, Pg No: 206) The way the inhabitants gain blessings from His feet, in the same way, the dwellers of the spiritual world seek the blessings of His feet.
"Hadhrat Imam Jalauddin Suyuti (May Allah shower His Mercy on him) says: When the Holy Prophet Sallallahualaihi wa sallam went on His heavenly Journey Meraj, the ‘Arsh clutched at His feet and said: “O Prophet of Allah, You are going but I should also get something from You.” The angels also started requesting: "O Prophet of Allah, You are going but please make some arrangement for our consolation.” The souls of the Momineen (Arwah) also said, “O Prophet of Allah SWT, do not remain with the ‘Arsh alone, remember us as well.”
Allah SWT decreed, “O beloved Prophet, give something from your Noor to the Arsh so that it keeps gaining blessings from it. Give your shadow to the angels so that they can console themselves with it. As they don't have any sins this is enough for them. Human beings commit sins. Give your pure body to the inhabitants of earth so that they are protected from punishment. The following has been said for You. Allah SWT will not punish them as long as you are with them) Miladnama, by Hadhrat Muhaddith-e-Deccan (May Allah shower his mercy on him).
The blessings of His feet are not restricted within this world. Those blessings will continue to flow even in the spiritual world and even on the Day of Judgment. As Imam Muhammad bin Yousuf (May Allah shower His Mercy on him) says, "On the Day of Judgment, all the people will be gathered in Syria. Allah’s will behind taking the Holy Prophet (Sallallahu alaihi wa sallam) to Baitul Muqaddas (Masjid Aqsa) is that when His feet touch the place, on the Day of Judgment the Muslims can have some ease and comfort and because of the blessings of His feet, standing there will be easy for the Muslims.”
The Pride of the Muhaddithin, Abul Hasanaat Syed Abdullah Shah Sahab (May Allah shower His Mercy on him) says, "When the Day of Judgment will be established, it will be new for everybody. Such will be the terror and panic of that day everybody will cry out “Nafsi, Nafsi” O my self, O my self. But the Holy Prophet (Sallallahu alaihi wa sallam) has already seen everything, so He (Sallallahu alaihi wa sallam) will not have any fear or terror. He (Sallallahu alaihi wa sallam) will say, Ummati, Ummati, “My followers, My followers” and will calmly intercede for the sinners.” (Merajnama by Muhaddith-e-Deccan) One among the names of the Holy Prophet (Sallallahu alaihi wa sallam) is Hashir. About this name, the Holy Prophet (Sallallahu alaihi wa sallam) says, “People will be gathered near my feet.” (i.e. before Me.)
