Zakaah is to purify one's position of wealth by distributing a prescribed amount which has to be given to the poor as a fundamental act of worship. Zakaat is one of the five compulsory pillars of Islam. The amount of wealth which makes one liable for Zakaat is called Nisaab.
The payment of Zakaat is compulsory on the excess wealth or effects which is equal to/or exceeds the value of Nisaab, and which is possessed for a full Islamic year. The rate of Zakaat which was fixed by Rasulullah  is 2.5%

Zhamb is a unit measure for sin. The more severe or grave the sin the more the Zhamb it attracts and thus punishment. We must repent to Allah for our sins and ask forgiveness for not fulfilling His rights. We must also ask forgiveness from all people who we have wronged and recompense any unfulfilled rights.

Islam recognises the natural desire of sexual relationship and promotes marriage between different sexes and therefore prohibits celibacy. However extra marital relationships (Adultery) or anything that may lead to any form of carnal desire, intimacy or relationship outside of marriage has been prohibited.

Allah says in the Holy Qur’aan:

"And come not near unto adultery, verily! It is an obscenity and an evil way." (17:32)

All practises, things and institutions which aid and foster fornication and immodesty are forbidden by Islam. There are different categories of this abominable crime of Zina. Our Holy Nabi said:

"The Zina of the eyes is to gaze (at that which is unlawful, e.g., nudity). The Zina of the ears is to listen (to talks of nudity which excites the carnal desire). The Zina of the tongue is to speak (what is evil). The Zina of the hand is to touch (the female which is unlawful to you). The Zina of the feet is to walk (towards immorality). The Zina of the heart is to desire (what is unlawful), and it is the private part which either commits or shuns the actual act of fornication." (Muslim)

Islam has made easy upon us the beautiful pathway to chastity, purity and piety (taqwa), by declaring unlawful all those factors that contribute to the commission of zina. The solution is simple: marriage, a fortress against all evils of the loins.

Ziyaarah (Seeing) is synonymous to visiting people or places.

Visiting Madinah Munawwara and presenting oneself in the Sacred Court of Rasulullah in The Prophet's Masjid by performing Ziyarat of the sacred Qabar (grave) is indeed among the greatest blessings and fortunes for a Muslim.

"My shafa’at (intercession on the Day of Qiyamah) is Waajib (on me) for the one who visits my grave." Hadeeth

Visiting other cemeteries/graves and praying for the dead in accordance with shariah is also highly recommended.

"You should not undertake a special journey to visit any place other than the following three Masajid with the expectation of receiving greater reward: the Sacred Masjid of Makkah, this Masjid of mine (Madinah), and Masjid al-Aqsa" (of Jerusalem-Old City, Occupied Palestine) Hadeeth
