Muslims have taken great care in preserving the sayings of Prophet Muhammad (PBUH) by committing them both to memory and to paper. Indeed, highly skilled memorizers and scholars demonstrated unmatched commitment to writing them down with the utmost care. By so doing, they presented the world with a superb system of verifying statements, distinguishing the genuine form the fabrications. The process focused on the minutest details of sentences and words, determining whatever additions have crept into them.
The following are examples of some of Prophet Muhammad’ sayings:
“Actions are but by intentions, and every person will have but that which they intend” (Al-Bukhari: 1)
“Righteousness is good morality, and wrongdoing is that which wavers in your soul and which you dislike people finding out about” (Muslim: 2553)
“Obey God wherever you are, follow up a bad deed with a good one and it will wipe it out, and behave well towards people” (At-Tirmidhi: 1987).
“Be indifferent to this world, and God will love you. Be indifferent to what is in people’s possession and they will love you” (Ibn Majah: 4102).
“My similitude in comparison with the prophets before me is that of a person who constructed a building that was quite imposing and beautiful and made it complete but for one brick in one of its corners. People went round it, admiring it and saying, ‘If only that brick were put in its place.’ I am that brick and I am the last of the prophets” (Al-Bukhari: 3342).
“If anyone relieves a believer of some worldly hardship, God will relieve him of some of the hardships of the Day of Judgement. If anyone makes it easy for a debtor, God will make it easy for him in this life and in the hereafter, and if anyone conceals the faults of a Muslim, God will conceal his faults in this world and in the hereafter. God helps His slave as long as he helps his brother, and if anyone follows a path in pursuit of knowledge, God will make easy for him a path to paradise …” (Muslim: 2699).
“None of you will truly believe until you love for your brother what you love for yourself” (Al-Bukhari: 13)
“A true Muslim is one does not harm Muslims with his tongue and hands, and a an emigrant, [besides being one who leaves his country,] is one who leaves what God has forbidden” (Al-Bukhari: 10).
“You will not enter Paradise until you believe, and you will not truly believe until you love one another. Shall I show you something which, if you do, you will love one another? Extend the greeting of peace to one another” (Muslim: 54).
"Do not wrong a non-Muslim, force him to work beyond his capacity, or take anything from him without his consent. If you do, I will plead for him on the Day of Judgement” (Abu Dawud: 3052).
“The merciful will be shown mercy by the Most Merciful. Show mercy to those on the earth, and the One above the heavens will show mercy to you” (Abu Dawud: 4941).
“Whoever who does not show mercy to our young ones or recognise the rights of our elders is not one of us” (At-Tirmidhi: 1920).
“Whoever cheats is not one of us” (At-Tirmidhi: 1315).
“In their mutual kindness, compassion and sympathy, the believers are like one body. When one of the limbs aches, the whole body responds to it with sleeplessness and fever” (Muslim: 2586).
“All of you are guardians and are responsible for your wards. The ruler is a guardian and is responsible for his subjects; a man is a guardian and is responsible for his family; a woman is a guardian and is responsible for her husband’s house and his offspring. Thus, all of you are guardians and are responsible for your wards” (Al-Bukhari: 4892).
“The believers with perfect faith are those who have the best manners, and the best of you are those who treat their wives the best” (At-Tirmidhi: 1162).
“The best of you are those who are the best at treating their wives, and, of all of you, I am the best at treating my wives” (At-Tirmidhi: 3895).
“God loves kindness and gentleness in every matter.” (Al-Bukhari: 5678);
“He who is deprived of forbearance and gentleness is deprived of all good” (Muslim: 2592).
“The signs of a hypocrite are three: Whenever he speaks, he tells a lie; whenever he makes a promise, he breaks it; and whenever he is entrusted with something, he betrays the trust” (Al-Bukhari: 33).
“Part of someone’s being a good Muslim is his leaving alone that which does not concern him” (At-Tirmidhi, 2317).
“While a man was walking along a road, he became very thirsty. He soon found a well, so He lowered himself into it, drank his fill and came out. Then he saw a dog panting and eating mud because of excessive thirst. The man said to himself, ‘This dog has become just as exhausted from thirst as I.’ He lowered himself into the well again, filled his shoe with water and gave the dog some water to drink. God accepted this good deed from him and forgave him.” The people asked, “Messenger of God! Will we be rewarded for taking care of animals?” “Yes,” he replied, “You will be rewarded for taking care of every living thing” (Al-Bukhari: 2466).
