  يَا أَيُّهَا ٱلَّذِينَ آمَنُوا لَا يَسْخَرْ قَوْمٌ مِنْ قَوْمٍ عَسَى أَنْ يَكُونُوا خَيْرًا مِنْهُمْ وَلَا نِسَاءٌ مِنْ نِسَاءٍ عَسَى أَن يَكُنَّ خَيْرًا مِنْهُنَّ وَلَا تَلْمِزُوا أَنْفُسَكُمْ وَلَا تَنَابَزُوا بِٱلْأَلْقَابِ
  yā ʔayyuhā llaḏīna ʔāmanū lā yasḵar qawmun min qawmin ʕasā ʔan yakūnū ḵayran minhum wa-lā nisāʔun min nisāʔin ʕasā ʔan yakunna ḵayran minhunna wa-lā talmizū ʔanfusakum wa-lā tanābazū bi-l-ʔalqābi
  O you who have believed, let not a people ridicule people; perhaps they may be better than them; nor let women ridicule women; perhaps they may be better than them. And do not insult one another and do not call each other by names.
- Zuhayr ibn Abi Sulma

Usage notes

As shown in the example, sense 4 generally governs a noun in the determinate state (but without the definite article) and the accusative case — that is, a noun without nunation. However, subsequent adjectives are in the indeterminate state, meaning they are nunated:

لَا طَالِبَ مُجْتَهِدًا حَاضِرٌ
lā ṭāliba mujtahidan ḥāḍirun
No hard-working student is present.

If, instead of an adjective, there is an attributive prepositional phrase, the initial noun can be in either state:

لَا طَالِبَ لَدَيْنَا مُجْتَهِدًا حَاضِرٌ
lā ṭāliba ladaynā mujtahidan ḥāḍirun
No hard-working student of ours is present.
لَا طَالِبًا لِلْعِلْمِ مُقَصِّرٌ
lā ṭāliban lilʕilmi muqaṣṣirun
No seeker of knowledge is delinquent.

Additionally, sense 4 can govern a preposition alone, with an implicit third-person singular masculine subject and no visible case or state. This is the origin of لَا عَلَيْكَ (lā ʕalayka, “no worries”, literally “there is not [anything] on you”) and similar collocations.
