RibaRiba (ربا ,الربا، الربٰوة ALA, ˈrɪbæː) is an Arabic word that can be roughly translated as "usury", or unjust, exploitative gains made in trade or business under Islamic law. Riba is mentioned and condemned in several different verses in the Qur'an (3:130, 4:161, 30:39 and perhaps most commonly in 2:275-2:280). It is also mentioned in many hadith (reports describing the words, actions, or habits of the Islamic prophet Muhammad). While Muslims agree that riba is prohibited, not all agree on what precisely it is.
WuduWuḍūʾ (الوضوء ALA-LC wʊˈdʕuːʔ) is the Islamic procedure for cleansing parts of the body, a type of ritual purification, or ablution. The 4 Fardh (Mandatory) acts of Wudu are: washing the face, then the arms, then wiping the head, then washing or wiping the feet, and doing these in order, without any big breaks between them. Wudu is an important part of ritual purity in Islam. It is governed by fiqh (Islamic jurisprudence), which specifies rules concerning hygiene and defines the rituals that constitute it.
SunnahIn Islam, sunnah, also spelled sunna (سنة), are the traditions and practices of the Islamic prophet Muhammad that constitute a model for Muslims to follow. The sunnah is what all the Muslims of Muhammad's time evidently saw and followed and passed on to the next generations. According to classical Islamic theories, the sunnah are documented by hadith (the verbally transmitted record of the teachings, deeds and sayings, silent permissions or disapprovals of Muhammad), and alongside the Quran (the book of Islam) are the divine revelation (Wahy) delivered through Muhammad that make up the primary sources of Islamic law and belief/theology.
