The Hadith of a year having to pass before giving Zakaat on wealth is not rigorously authenticated
Among the conditions for the Zakaat to become Wajib (compulsory) is that a year should pass on the wealth. This condition is compulsory in the opinion of the non-followers as well. The Hadith used to prove this is weakly authenticated. Imam Baihaqui has written:
Translation: Zakaat does not become Wajib on any wealth until a year has passed on it…………….In the chain of narration of this Hadith, there is Haritha, on whose narrations deductions cannot be based. In this issue, the Traditions narrated on the authority of Hadhrat Abu Bakr Siddiq, Hadhrat ‘Uthman, Hadhrat ‘Abdullah bin ‘Umar and other Companions are considered. (As Sunan Ul Kubra Lil Baihaqui, Kitab Uz Zakaat, Babu La Zakaata Fi Malin Hatta Yahoola ‘Alaihil Haul, Vol. 4, Pg. No. 160, Hadith No. 7274)
Another Hadith of the same meaning has come from A’asim bin Dhamra and Imam Baihaqui writes about him:
Translation: A’asim bin Dhamra (i.e. his narrations are) not worthy of being deduced from. (As Sunan Ul Kubra Lil Baihaqui, Kitab Us Salaat, Babu Mabdai Fardhit Tashhahud)
He also said:
Translation: Hadhrat ‘Abdullah bin Mubarak (May Allah shower His mercy on him) has declared him unreliable. (As Sunan Ul Kubra Lil Baihaqui, Kitab Us Salaat, Babul Khabaril Ladhee Ja'a Fis Salaat)
Another Hadith in this context is narrated on the authority of Harith bin ‘Abdullah. Imam Baihaqui (May Allah shower His mercy on him) clarifies about this:
Translation: Harith A’awar is unreliable. (As Sunan Ul Kubra Lil Baihaqui, Kitab Ut Taharah, Babu Man’it Tatahhuri Bin Nabeedh)
It has been mentioned on the authority of Imam Sha’abi:
Translation: Imam Sha’abi has said that Harith is a liar. (As Sunan Ul Kubra Lil Baihaqui, Kitab Ul Qasama, Babu Aslil Qasamati Wal Bida’ati Feeha)
‘Allama Haithami writes after mentioned a similar Hadith in Mo’jam Tabarani:
Translation: In the chain of narration of this Hadith, there is ‘Ambasa bin ‘Abdur Rahman who is an unreliable narrator. (Majma Uz Zawaaid Wa Mamba’ Ul Fawaaid Kitab Uz Zakaat, Babu Mata Tajibuz Zakaat)
Thus, the Marfu’ Hadith of 1 year having to pass for the Zakaat to become Wajib is not free of unreliability, but still the non-followers base their deductions on it.
