Everything that can be counted is considered little, as the big amount is uncountable, as Allah U has said:

﴾وَإِنْ تَعُدُّوا نِعْمَةَ اللَّهِ لا تُحْصُوهَا﴿

“If you enumerate Allah’s blessings, you will not be able to count them.” [Surah Ibrahim: 34]

Whereas He says of the little which can be counted:

﴾وَشَرَوْهُ بِثَمَنٍ بَخْسٍ دَرَاهِمَ مَعْدُودَةٍ﴿

“And they sold him for a cheap price, a few dirhams, for they set small store by him. ˮ [Surah Yusuf: 20]

 The price mentioned here is only a little.

In this verse, these Israelites seek that their charge on the Day of Judgment will only span a few days consisting of a small punishment.

﴾قُلْ أَاتَّخَذْتُمْ عِنْدَ اللَّهِ عَهْداً فَلَنْ يُخْلِفَ اللَّهُ عَهْدَهُ﴿ “Say, ‘Have you taken a covenant with Allah? For Allah will never break His covenant’”: This is because, Allah U will not break the covenant and promise.

﴾أَمْ تَقُولُونَ عَلَى اللَّهِ مَا لا تَعْلَمُونَ﴿ “Or do you say about Allah that which you do not know?”
