Suuratul – Furqaan Verse 63.
وَعِبَادُ ٱلرَّحْمَـٰنِ ٱلَّذِينَ يَمْشُونَ عَلَى ٱلْأَرْضِ هَوْنًا وَإِذَا خَاطَبَهُمُ ٱلْجَـٰهِلُونَ قَالُوا۟ سَلَـٰمًا ﴿٦٣
63. And the slaves of the Most Beneficent (Allah) are those who walk on the earth in humility and dignity, and when the foolish address them (with bad words) they reply back with mild words of gentleness.
Tafsir Ibn Kathir Volume 7, Page 196.
These are the attributes of the believing servants of Allah,
﴿الَّذِينَ يَمْشُونَ عَلَى الاٌّرْضِ هَوْناً﴾
(those who walk on the earth Hawna,) meaning that they walk with dignity and humility, not with arrogance and pride. This is like the Ayah:
﴿وَلاَ تَمْشِ فِى الاٌّرْضِ مَرَحًا﴾
(And walk not on the earth with conceit and arrogance…) (17:37).
So these people do not walk with conceit or arrogance or pride. This does not mean that they should walk like sick people, making a show of their humility, for the leader of the sons of Adam (the Prophet) used to walk as if he was coming downhill, and as if the earth were folded up beneath him. What is meant here by Hawn is serenity and dignity, as the Messenger of Allah said:
«إِذَا أَتَيْتُمُ الصَّلَاةَ فَلَا تَأْتُوهَا وَأَنْتُمْ تَسْعَونَ، وَأْتُوهَا وَعَلَيْكُمُ السَّكِينَةُ فَمَا أَدْرَكْتُمْ مِنْهَا فَصَلُّوا، وَمَا فَاتَكُمْ فَأَتِمُّوا»
(When you come to the prayer, do not come rushing in haste. Come calmly and with tranquility, and whatever you catch up with, pray, and whatever you miss, make it up.)
﴿وَإِذَا خَاطَبَهُمُ الجَـهِلُونَ قَالُواْ سَلاَماً﴾
(and when the foolish address them they say: “Salama”)
If the ignorant people insult them with bad words, they do not respond in kind, but they forgive and overlook, and say nothing but good words. This is what the Messenger of Allah did: the more ignorant the people, the more patient he would be. Then Allah says that their nights are the best of nights, as He says:
﴿وَالَّذِينَ يِبِيتُونَ لِرَبِّهِمْ سُجَّداً وَقِيَـماً ﴾
(And those who spend the night in worship of their Lord, prostrate and standing)
Meaning, worshipping and obeying Him. This is like the Ayat:
﴿كَانُواْ قَلِيلاً مِّن الَّيْلِ مَا يَهْجَعُونَ – وَبِالاٌّسْحَـرِ هُمْ يَسْتَغْفِرُونَ ﴾
(They used to sleep but little by night. And in the hours before dawn, they were asking for forgiveness) (51:17-18).
﴿تَتَجَافَى جُنُوبُهُمْ عَنِ الْمَضَاجِعِ﴾
(Their sides forsake their beds…) (32:16).
﴿أَمَّنْ هُوَ قَانِتٌ ءَانَآءَ الَّيْلِ سَـجِداً وَقَآئِماً يَحْذَرُ الاٌّخِرَةَ وَيَرْجُواْ رَحْمَةَ رَبِّهِ﴾
(Is one who is obedient to Allah, prostrating himself or standing during the hours of the night, fearing the Hereafter and hoping for the mercy of his Lord…) (39:9).
