1. Sayyiduna Umar Farooq (radi Allahu anhu) narrated that our beloved Prophet (sallal laahu alaihi wasallam) said that the loss of wealth that one suffers on land or sea is due to not paying Zakaah. (Tibraani)
2. Abu Hurairah (radi Allahu anhu) narrated that our beloved Prophet (sallal laahu alaihi wasallam) said that three persons would enter the Hell first. One of them, is the person who does not give Allah’s rightful share (Zakaah & Sadaqah) from his wealth. (Ibn-e-Khazema & Habaan)
3. Sayyiduna Abu Hurairah (radi Allahu anhu) narrated that our beloved Prophet (sallal laahu alaihi wasallam) said that wealth does not decrease when you give Sadaqah; and Allah increases the esteem of the one who forgives other people’s mistakes; and Allah raises the status of the one who practices humbleness for His sake. (Bukhari & Muslim)
4. Sayyiduna Abu Ayyub (radi Allahu anhu) narrated that a man asked the Prophet (sallal laahu alaihi wasallam) about a deed that would take him to Heaven. Our beloved Prophet (sallal laahu alaihi wasallam) replied: Pray to Allah. Do not commit Shirk (do not hold any partners with Him), keep performing Salaah, give Zakaah, and be kind to everyone. (Riyad-us-Saliheen)
5. Sayyiduna Abdullah bin Masu’d (radi Allahu anhu) has said that we were commanded to perform Salaah and give Zakaah, and that Salah is not accepted of the person who does not give Zakaah despite eligibility. (Tibraani)
6. Bazzaz narrated from Sayyiduna Alqamah (radi Allahu anhu) reporting that our beloved Prophet (sallal laahu alaihi wasallam) has said that the completion of one’s Islam is dependent upon giving away Zakaah from one’s wealth.
It is stated in the Hadith that by giving Zakaah the following benefits are derived:
1. Gain the pleasure of Allah,
2. Increase in wealth and protection from losses,
3. Allah’s forgiveness and blessings,
4. Protection from the wrath of Allah and from a bad death,
5. A shelter on the Day of Judgment,
6. Security from seventy misfortunes.
Just as Salaah is the most important act of worship, which has to be performed bodily, so is Zakaah the main act of worship which has to be performed monetarily. Those who fulfill this duty have been promised abundant reward in this world and Hereafter. Whoever evades Zakaah has been sternly warned in the Qur’an and Hadith of the consequences.
Linguistically, Zakaah has two meanings: purification and growth. Technically, it means to purify one’s possession of wealth by distributing a prescribed amount to the poor, the indigent, the slaves or captives, and the wayfarer.
