Obligation of qurbani for someone who owns T.V ?
For qurbani to become obligatory, is the potential of growth (ﻧﻤﺎء) in the items one possesses a condition? For example, a poor person (who’s not in debt) owns a T.V. (which was not purchased with the intention of resale) which is worth more than the nisab amount and is beyond his necessities. Will qurbani be obligatory for such an individual? Answer: ﺑﺴﻢ اﷲ اﻟﺮﺣﻤﻦ اﻟﺮﺣﯿﻢ In the name of Allah, the Most Gracious, the Most Merciful
Potential of growth (ﻧﻤﺎء) is not a condition for the obligation of qurbani. It is mentioned in Qurbani Laws Made Easy: “Qurbaani is compulsory upon every understanding, mature, resident Muslim male and female who owns nisaab or owns extra items (over and above their need) which equals the nisaab amount, i.e. they own an amount that equals the gold and silver nisaab amount, or they possess homes or properties besides the one they live in or they have extra household items that equal the nisaab amount or they have trading stock, shares etc. Then one share of Qurbaani is necessary for them to do. It is not a condition for a year to pass over the nisaab amount or the items that are over and above one's needs. It is also not a condition for the goods to be trading stock. If a person becomes the owner of it before sunset of the 12th of Dhul Hijjah, then Qurbaani is compulsory upon him/her. From the three days of Qurbaani, if a person becomes the owner of nisaab even on the last day, or he becomes the owner of goods that are over and above his needs, then Qurbaani becomes compulsory upon him. If a person has a home other than the one he lives in, whether it is for trade or not, or he has a flat besides the one he lives in, he has a vehicle other than what he needs, then this person is a saahib-e-nisaab with regards to Qurbaani. Qurbaani is compulsory upon him.”  Hence, qurbani will be obligatory for the individual mentioned in the example because a T.V. is not considered a necessity of life, and its value reached nisab.
