These are the attributes of the believing servants of Allah,

meaning that they walk with dignity and humility, not with arrogance and pride. This is like the Ayah :

{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:

«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.»

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. This is as Allah says:

{And when they hear Al-Laghw (evil or vain talk), they withdraw from it} (28:55).

Then Allah says that their nights are the best of nights, as He says:

meaning, worshipping and obeying Him. This is like the Ayat

{They used to sleep but little by night. And in the hours before dawn, they were asking for forgiveness } (51:17-18).

{Their sides forsake their beds...} (32:16).

{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).

Allah says:

meaning, ever-present and never ending.

Al-Hasan said concerning the Ayah,

Everything that strikes the son of Adam, then disappears, does not constitute an inseparable, permanent punishment. The inseparable, permanent punishment is that which lasts as long as heaven and earth. This was also the view of Sulayman At-Taymi.
