The word عدد in the Quran

هُوَ ٱلَّذِى جَعَلَ ٱلشَّمْسَ ضِيَآءً وَٱلْقَمَرَ نُورًا وَقَدَّرَهُۥ مَنَازِلَ لِتَعْلَمُوا۟ عَدَدَ ٱلسِّنِينَ وَٱلْحِسَابَ مَا خَلَقَ ٱللَّهُ ذَٰلِكَ إِلَّا بِٱلْحَقِّ يُفَصِّلُ ٱلْـَٔايَٰتِ لِقَوْمٍ يَعْلَمُونَ ۝٥

It is He who made the sun a shining light and the moon a derived light and determined for it phases - that you may know the number of years and account [of time]. Allāh has not created this except in truth. He details the signs for a people who know.

وَجَعَلْنَا ٱلَّيْلَ وَٱلنَّهَارَ ءَايَتَيْنِ فَمَحَوْنَآ ءَايَةَ ٱلَّيْلِ وَجَعَلْنَآ ءَايَةَ ٱلنَّهَارِ مُبْصِرَةً لِّتَبْتَغُوا۟ فَضْلًا مِّن رَّبِّكُمْ وَلِتَعْلَمُوا۟ عَدَدَ ٱلسِّنِينَ وَٱلْحِسَابَ وَكُلَّ شَىْءٍ فَصَّلْنَٰهُ تَفْصِيلًا ۝١٢

And We have made the night and day two signs, and We erased the sign of the night and made the sign of the day visible that you may seek bounty from your Lord and may know the number of years and the account [of time]. And everything We have set out in detail.

فَضَرَبْنَا عَلَىٰٓ ءَاذَانِهِمْ فِى ٱلْكَهْفِ سِنِينَ عَدَدًا ۝١١

So We cast [a cover of sleep] over their ears within the cave for a number of years.

قَٰلَ كَمْ لَبِثْتُمْ فِى ٱلْأَرْضِ عَدَدَ سِنِينَ ۝١١٢

[Allāh] will say, "How long did you remain on earth in number of years?"

حَتَّىٰٓ إِذَا رَأَوْا۟ مَا يُوعَدُونَ فَسَيَعْلَمُونَ مَنْ أَضْعَفُ نَاصِرًا وَأَقَلُّ عَدَدًا ۝٢٤

[The disbelievers continue] until, when they see that which they are promised, then they will know who is weaker in helpers and less in number.

لِّيَعْلَمَ أَن قَدْ أَبْلَغُوا۟ رِسَٰلَٰتِ رَبِّهِمْ وَأَحَاطَ بِمَا لَدَيْهِمْ وَأَحْصَىٰ كُلَّ شَىْءٍ عَدَدًۢا ۝٢٨

That he [i.e., Muḥammad (ﷺ)] may know that they have conveyed the messages of their Lord; and He has encompassed whatever is with them and has enumerated all things in number.

ٱلَّذِى جَمَعَ مَالًا وَعَدَّدَهُۥ ۝٢

Who collects wealth and [continuously] counts it.
