By Yusuf Estes, Former Christian Preacher
O2. Muhammad r never committed adultery, and he required his followers to engage only in lawful marriage relationships with women, and forbade sex outside of Almighty God's Ordinance.
“Satan threatens you with poverty and orders you to commit evil deeds; whereas Allah promises you Forgiveness from Himself and Bounty, and Allah is All-Sufficient for His creatures' needs, All-Knower.” (Chapter 2, Verse 268)
Say (O Muhammad): "(But) the things that my Lord has indeed forbidden are evil acts, whether committed openly or secretly, sins (of all kinds), unrighteous oppression, joining partners (in worship) with Allah for which He has given no authority, and saying things about Allah of which you have no knowledge." (Chapter 7, Verse 33.)
O Prophet! When believing women come to you to give you the pledge, that they will not associate anything in worship with Allah, that they will not steal, that they will not commit illegal sexual intercourse, that they will not kill their children, that they will not utter slander, intentionally forging falsehood, and that they will not disobey you in any good then accept their pledge, and ask Allah to forgive them, Verily, Allah is Oft-Forgiving, Most Merciful. (Chapter 60, Verse 12)
People committed fornication and adultery in most places around the word in Muhammad's time, yet he never once did so, and he forbade all of his followers from this evil practice.
P2. Muhammad r forbade usury and interest on money lending, as Jesus u had done centuries before him. It can be easily shown throughout history, how usury eats away at wealth and destroys the economic systems. Therefore, just as in the teachings of the Prophets of old, Muhammad r held that such practices were most evil and must be avoided in order to be at peace with the Creator (Allah).
“Those who eat usury (deal in interest) will not stand (on the Day of Resurrection) except like the standing of a person beaten by Satan leading him to insanity. That is because they say: "Trading is only like usury," whereas Allah has permitted trading and forbidden usury.
So whosoever receives an admonition from his Lord and stops eating usury shall not be punished for the past; his case is for Allah (to judge); but whoever returns to dealing in usury, such are the dwellers of the Fire - they will abide therein.
Allah will destroy usury and will give increase. And Allah likes not the disbelieving sinners.
Truly those who believe, and do deeds of righteousness, and perform prayer, and give charity, they will have their reward with their Lord. On them shall be no fear, nor shall they grieve.
O you who believe! Be afraid of Allah and give up what remains (due to you) from usury, if you are believers. And if you do not do it, then take a notice of war from Allah and His Messenger but if you repent, you shall have your capital sums. Deal not unjustly, and you shall not be dealt with unjustly.” (Chapter 2: Verses 275 – 279)
Q2. Muhammad r never gambled and did not allow it. Like usury, gambling takes away wealth but at an even faster pace.
"People ask you (Muhammad) about alcohol and gambling. Say, 'There is great sin in both of them and (some benefit) for humans, but the sin is greater than any benefit from them.' And they ask you what they should spend. Say, 'Whatever is above your basic needs.' So, Allah makes it clear to you His Laws in order for you to give thought."
(Chapter 2: Verse 219)
Gambling had not been viewed as so evil until the time of Muhammad r. Today, it is well known the damage gambling causes to families and even mental health. The idea of getting something for nothing is not the proper way of life prescribed by the teachings of Muhammad r.
