Islam: Goodness, Justice, and Strength
Islam always teaches us to have good morals, to be kind to people, and to invite them to the path of guidance with good words.
(And speak to people good [words]) Quran, chapter 2, verse 83.
(And do good; indeed, Allah loves the doers of good.) Quran, chapter 2, verse 195.
(And who is better in speech than one who invites to Allah and does righteousness and says, "Indeed, I am of the Muslims.") Quran, chapter 41, verse 33.
(Invite to the way of your Lord with wisdom and good instruction, and argue with them in a way that is best. Indeed, your Lord is most knowing of who has strayed from His way, and He is most knowing of who is [rightly] guided.) Quran, chapter 16, verse 125.
The Messenger of Allah (ﷺ) said: "The best of people are the most beneficial to others."
Islam also teaches us to be strong so that we can defend ourselves and protect helpless people.
(And prepare against them whatever you are able of power and of steeds of war by which you may terrify the enemy of Allah and your enemy and others besides them whom you do not know.) Quran, chapter 8, verse 60.
The Messenger of Allah (ﷺ) said: "A believer who is strong (and healthy) is better and dearer to Allah than the weak believer, but there is goodness in both of them."
(Fight against them until there is no more oppression and [until] worship is [acknowledged to be] for Allah. But if they cease, then there is to be no aggression except against the oppressors.) Quran, chapter 2, verse 193.
Islam always warns against corruption and attacking others without justification, even if they are non-believers.
(O you who have believed, do not consume one another's wealth unjustly but only [in lawful] business by mutual consent. And do not kill yourselves [or one another].) Quran, chapter 4, verse 29.
(So fulfill the measure and weight and do not deprive people of their due and cause not corruption upon the earth after its reformation. That is better for you, if you should be believers.) Quran, chapter 7, verse 85.
(Fight in the way of Allah those who fight you but do not transgress. Indeed. Allah does not like transgressors.) Quran, chapter 2, verse 190.
(And cause not corruption upon the earth.) Quran, chapter 7, verse 65.
(But seek, through that which Allah has given you, the home of the Hereafter; and [yet], do not forget your share of the world. And do good as Allah has done good to you. And desire not corruption in the land. Indeed, Allah does not like corrupters.) Quran, chapter 28, verse 77.
