Messenger of Allah ﷺ said, "No Zakat is imposed on less than five Awsuq of dates; no Zakat is imposed on less than five Awaq of silver, and no Zakat is imposed on less than five camels." (Using translation from Bukhārī 1459)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَيْسَ فِيمَا دُونَ خَمْسِ أَوَاقٍ مِنَ الْوَرِقِ صَدَقَةٌ وَلَيْسَ فِيمَا دُونَ خَمْسِ ذَوْدٍ مِنَ الْإِبِلِ صَدَقَةٌ وَلَيْسَ فِيمَا دُونَ خَمْسَةِ أَوْسُقٍ مِنَ التَّمْرِ صَدَقَةٌ  

[Machine] The Prophet Muhammad ﷺ said, "There is no charity in less than five awqas, and there is no charity in less than five dawds." Sufyan said, "And the average awqiya is forty dirhams."  

قَالَ رَسُولُ اللهِ ﷺ لَيْسَ فِيمَا دُونَ خَمْسِ أَوَاقٍ صَدَقَةٌ وَلَيْسَ فِيمَا دُونَ خَمْسِ ذَوْدٍ صَدَقَةٌ قَالَ سُفْيَانُ وَالْأُوقِيَّةُ أَرْبَعُونَ دِرْهَمًا  

That the Apostle of Allaah ﷺ as saying No sadaqah(zakat) is payable on less than five camels, on less than five ounces of silver and on less than five camel loads(wasq). (Using translation from Abū Dāʾūd 1558)   

قَالَ رَسُولُ اللهِ ﷺ لَيْسَ فِيمَا دُونَ خَمْسِ ذَوْدٍ صَدَقَةٌ وَلَيْسَ فِيمَا دُونَ خَمْسِ أَوَاقٍ صَدَقَةٌ وَلَيْسَ فِيمَا دُونَ خَمْسَةِ أَوْسُقٍ صَدَقَةٌ
