Abu Bakr wrote to me what Allah's Messenger (ﷺ) has made compulsory (regarding Zakat) and this was mentioned in it: If a property is equally owned by two partners, they should pay the combined Zakat and it will be considered that both of them have paid their Zakat equally.
Sahih al-Bukhari Book 24, Hadith 54
← Previous Hadith Abu Bakr wrote to me what was made compulsory by Allah's Messenger (ﷺ) and that was (regarding the payments of Zakat): Neither the property of different people may be taken together nor the joint property may be split for fear of (paying more, or receiving less) Zakat.

Sahih al-Bukhari Book 24, Hadith 53 Next Hadith → A Bedouin asked Allah's Messenger (ﷺ) about the emigration. The Prophet (p.b.u.h) said, "May Allah have mercy on you! The matter of emigration is very hard. Have you got camels? Do you pay their Zakat?" The Bedouin said, "Yes, I have camels and I pay their Zakat." The Prophet (ﷺ) said, Work beyond the seas and Allah will not decrease (waste) any of your good deeds." (See Hadith No. 260 Vol. 5).
