PREPARATIONS FOR RELEGIOUS DUTIES (Cleanness)
[5:6] O you who believe, when you observe the Contact Prayers (Salat), you shall: (1) wash your faces, (2) wash your arms to the elbows, (3) wipe your heads, and (4) wash your feet to the ankles. If you were unCLEAN due to sexual orgasm, you shall bathe. If you are ill, or traveling, or had any digestive excretion (urinary, fecal, or gas), or had (sexual) contact with the women, and you cannot find water, you shall observe the dry ablution (Tayammum) by touching CLEAN dry soil, then rubbing your faces and hands. GOD does not wish to make the religion difficult for you; He wishes to CLEANse you and to perfect His blessing upon you, that you may be appreciative.
What Nullifies Ablution
[4:43] O you who believe, do not observe the Contact Prayers (Salat) while intoxicated, so that you know what you are saying. Nor after sexual orgasm without bathing, unless you are on the road, traveling; if you are ill or traveling, or you had urinary or fecal-related excretion (such as gas), or contacted the women (sexually), and you cannot find water, you shall observe Tayammum (dry ablution) by touching CLEAN dry soil, then wiping your faces and hands therewith. GOD is Pardoner, Forgiver.
[2:222] They ask you about menstruation: say, "It is harmful; you shall avoid sexual intercourse with the women during menstruation; do not approach them until they are rid of it. Once they are rid of it, you may have intercourse with them in the manner designed by GOD. GOD loves the repenters, and He loves those who are clean."
PREPARATIONS FOR RELEGIOUS DUTIES (Dress code)
Dress Nicely For The Masjid
[7:31] O children of Adam, you shall be CLEAN and dress nicely when you go to the masjid. And eat and drink moderately; Surely, He does not love the gluttons.
Dress Code for Men
[24:30] Tell the believing men that they shall subdue their eyes (and not stare at the women), and to maintain their chastity. This is purer for them. GOD is fully Cognizant of everything they do.
Dress Code for Women
[24:31] And tell the believing women to subdue their eyes, and maintain their chastity. They shall not reveal any parts of their bodies, except that which is necessary. They shall cover their chests, and shall not relax this code in the presence of other than their husbands, their fathers, the fathers of their husbands, their sons, the sons of their husbands, their brothers, the sons of their brothers, the sons of their sisters, other women, the male servants or employees whose sexual drive has been nullified, or the children who have not reached puberty. They shall not strike their feet when they walk in order to shake and reveal certain details of their bodies. All of you shall repent to GOD, O you believers, that you may succeed.*
[33:59] O prophet, tell your wives, your daughters, and the wives of the believers that they shall lengthen their garments. Thus, they will be recognized (as righteous women) and avoid being insulted. GOD is Forgiver, Most Merciful.
Dress Code Relaxation
[24:60] The elderly women who do not expect to get married commit nothing wrong by relaxing their dress code, provided they do not reveal too much of their bodies. To maintain modesty is better for them. GOD is Hearer, Knower.
[33:55] The women may relax (their dress code) around their fathers, their sons, their brothers, the sons of their brothers, the sons of their sisters, the other women, and their (female) servants. They shall reverence GOD. GOD witnesses all things.
[4:82] Why do they not study the Quran carefully? If it were from other than GOD, they would have found in it numerous contradictions.
