And the servants of the Most Merciful are those who walk upon (25:63)

Almuntakhab Fi Tafsir Alquran Alkarim

(And how richly rewarded shall be: a) The worshippers of Allah who observe religious acts of worship enjoined by AL-Rahman; they walk on earth softly, gently and in humility. When addressed by the insolent and impudent whose imprudence gets the better of them, they answer them with the expression of good will «Peace»

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(25:63) The (true) servants of the Merciful are those *78 who walk humbly on the earth *79 who, when the ignorant people behave insolently towards them, say,"Peace to you" *80

And the servants of the Most Merciful are those who walk upon meaning

*78) That is, "Though all human beings are by birth the servants of the Merciful before Whom you have been invited to prostrate yourselves, and which you disdain, his true servants are those who adopt the way of His obedience consciously and develop such desirable characteristics. Then the natural consequences of the prostration are those found in the lives of the Believers and the evil results of rejecting the invitation, those found in your lives." Here attention is being drawn to the two patterns of character and life: first of those who had accepted the Message of the Holy Prophet and were following it, and the second of those who persisted in the ways of ignorance. Here only the prominent characteristics of the true Believers have been cited, and for contrast, the characteristics of the disbelievers have been left to every discerning eye and mind which could see them all around in society and make its own decision.
*79) That is; "They do not walk haughtily and arrogantly like the tyrants and mischief-makers, but their "gait" is of a gentle, right-thinking and goodnatured person." "Walking humbly" does not mean walking like a weak or sick person, nor does it imply the gait of a hypocrite who walks ostentatiously to show humility or fear of God. According to Traditions, the Holy Prophet himself used to walk with firm, quick steps. One day Caliph `Umar saw a young man walking slowly like a weak, sick person, and asked him, "Are you ill?" When the man replied in the negative, the Caliph raised his whip, rebuked him and told him to walk like a healthy man. This shows that the "humble gait" is the natural gait of a noble and gentle person and not a gait which shows weakness and undue humility. In this connection, the first characteristic of the true servants of Allah to which attention has been drawn, is their "gait" This is because the gait indicates the character of an individual. If a man walks in a humble and dignified way, as opposed to a haughty, vain and proud manner, it shows that he is a noble and gentle person. Thus the different "gaits" of the different types of people show what sort of characters they possess. The verse means to imply that the true servants of the Merciful can be easily recognized by their "gait" among the people. Their attitude of Allah's worship and obedience has changed them so thoroughly that it can "be seen at first sight from their "gate that they are noble, humble and good natured people, who cannot be expected to indulge in any mischief. For further explanation, see E.N.43 of Bani Isra'il and L.N 33 of Luqman
*80) "Ignorant people": Rude and insolent people and not uneducated and illiterate ones. The true servants of the "Merciful" do not believe in "vengeance", even though they may have to deal with the ignorant people who behave rudely and insolently towards them. If they happen to come across such people, they wish them peace and turn away. The same thing has been expressed in AI-Qasas: 55, thus: "And when they hear something vain and absurd they turn away from it, saying, `Our deeds are for us and your deeds are for you: peace be to you: we have nothing to do with the ignorant'." For details see E.N.'s 72 to 78 ul AI-Qasas.
