Nu'man bin Bashir (May Allah be pleased with him) reported: The Prophet (ﷺ) said, "The likeness of the man who observes the limits prescribed by Allah and that of the man who transgresses them is like the people who get on board a ship after casting lots. Some of them are in its lower deck and some of them in its upper (deck). Those who are in its lower (deck), when they require water, go to the occupants of the upper deck, and say to them : 'If we make a hole in the bottom of the ship, we shall not harm you.' If they (the occupants of the upper deck) leave them to carry out their design they all will be drowned. But if they do not let them go ahead (with their plan), all of them will remain safe". .

Umm Salamah (May Allah be pleased with her) reported: The Prophet (ﷺ) said, "You will have rulers some of whom you approve and some of whom you will disapprove.

Zainab (May Allah be pleased with her) reported: The Prophet (ﷺ) came to visit me one day frightened and he (ﷺ) said: "La ilaha illallah (There is no true God but Allah).

Abu Sa'id Al-Hasan Basri reported: 'Aidh bin 'Amr (the Companion) (May Allah be pleased with him) visited 'Ubaidullah bin Ziyad (the ruler) and said to him: "Son, I heard Messenger of Allah (ﷺ) saying, 'The worst shepherds (rulers) are those who deal harshly in respect of supervision. Beware, Don't be one of them!"' Ibn Ziyad said to him, "Sit down, you are but husk from among the Companions of the Prophet (ﷺ)."

Hudhaifah (May Allah bepleased with him) reported: The Prophet (ﷺ) said, "By Him in Whose Hand my life is, you either enjoin good and forbid evil, or Allah will certainly soon send His punishment to you.

'Abdullah bin Mas'ud (May Allah bepleased with him) reported: Messenger of Allah (ﷺ) said, "The first defect (in religion) which affected the Children of Israel in the way that man would meet another and say to him: 'Fear Allah and abstain from what you are doing, for this is not lawful for you.' Then he would meet him the next day and find no change in him, but this would not prevent him from eating with him, drinking with him and sitting in his assemblies. When it came to this, Allah led their hearts into evil ways on account of their association with others." Then he (ﷺ) recited, "Those among the Children of Israel who disbelieved were cursed by the tongue of Dawud (David) and 'Isa (Jesus), son of Maryam (Mary). That was because they disobeyed (Allah and the Messengers) and were ever transgressing beyond bounds. They used not to forbid one another from the Munkar (wrong, evildoing, sins, polytheism, disbelief) which they committed. Vile indeed was what they used to do. You see many of them taking the disbelievers as their Auliya' (protectors and helpers). Evil indeed is that which their own selves have sent forward before them; for that (reason) Allah's wrath fell upon them and in torment will they abide. And had they believed in Allah and in the Prophet (Muhammad (ﷺ)) and in what has been revealed to him, never would they have taken them (the disbelievers) as Auliya' (protectors and helpers); but many of them are the Fasiqun (rebellious, disobedient to Allah)." (5:78-81) Then he (ﷺ) continued: "Nay, by Allah, you either enjoin good and forbid evil and catch hold of the hand of the oppressor and persuade him to act justly and stick to the truth, or, Allah will involve the hearts of some of you with the hearts of others and will curse you as He had cursed them". . The wording in At-Tirmidhi is: Messenger of Allah (ﷺ) said, "When the Children of Israel became sinful, their learned men prohibited them but they would not turn back. Yet, the learned men associated with them and ate and drank with them. So, they were cursed at the tongues of Dawud and 'Isa (Jesus), son of Maryam (Mary), because they were disobedient and were given to transgression." At this stage Messenger of Allah (ﷺ) who was reclining on a pillow sat up and said, "No, By Him in Whose Hand my soul is, there is no escape for you but you persuade them to act justly."

Abu Bakr As-Siddiq (May Allah bepleased with him) reported: "O you people! You recite this Verse: 'O you who believe! Take care of your ownselves. If you follow the (right) guidance no hurt can come to you from those who are in error.' (5:105) But I have heard Messenger of Allah (ﷺ) saying: "When people see an oppressor but do not prevent him from (doing evil), it is likely that Allah will punish them all." .

Usamah bin Zaid (May Allah bepleased with them) reported: Messenger of Allah (ﷺ) said, "A man will be brought on the Day of Resurrection and will be cast into Hell, and his intestines will pour forth and he will go round them as a donkey goes round a millstone. The inmates of Hell will gather round him and say: 'What has happened to you, O so-and-so? Were you not enjoining us to do good and forbidding us to do evil?' He will reply: 'I was enjoining you to do good, but was not doing it myself; and I was forbidding you to do evil, but was doing it myself". .

Abu Hurairah (May Allah bepleased with him) reported: Messenger of Allah (ﷺ) said, "There are three signs of a hypocrite: When he speaks, he lies; when he makes a promise, he breaks it; and when he is trusted, he betrays his trust." . Another narration adds the words: 'Even if he observes fasts, performs Salat and asserts that he is a Muslim".

Hudhaifah bin Al-Yaman (May Allah bepleased with him) reported: Messenger of Allah (ﷺ) foretold to us two Ahadith. I have seen one (being fulfilled), and I am waiting for the other. He (ﷺ) told us, "Amanah (the trust) descended in the innermost (root) of the hearts of men (that is, it was in their heart innately, by Fitrah, or pure human nature). Then the Qur'an was revealed and they learnt from the Quran and they learned from the Sunnah." Then the (Prophet (ﷺ)) told us about the removal of Amanah. He said, "The man would have some sleep, and Amanah would be taken away from his heart leaving the impression of a faint mark. He would again sleep, and Amanah would be taken away from his heart leaving an impression of a blister, as if you rolled down an ember on your foot and it was vesicled. He would see a swelling having nothing in it." He (the Prophet (ﷺ)) then took up a pebble and rolled it over his foot and said, "The people would enter into transactions with one another and hardly a person would be left who would return (things) entrusted to him (and there would look like an honest person) till it would be said: 'In such and such tribe there is a trustworthy man.' And they would also say about a person: 'How prudent he is! How handsome he is and how intelligent he is!' whereas in his heart there would be no grain of Faith." Hudhaifah bin Al-Yaman (May Allah bepleased with him) added: I had a time when I did not care with whom amongst you I did business, I entered into a transaction, for if he were a Muslim, his Faith would compel him to discharge his obligation to me; and if he were a Christian or a Jew, his guardian (surety) would compel him to discharge his obligation to me. But today I would not enter into a transaction except with so-and-so. .
