In the name of Allah, the Beneficent, the Merciful
Allah said:
وَلْتَكُن مِّنكُمْ أُمَّةٌ يَدْعُونَ إِلَى الْخَيْرِ وَيَأْمُرُونَ بِالْمَعْرُوفِ وَيَنْهَوْنَ عَنِ الْمُنكَرِ وَأُولَٰئِكَ هُمُ الْمُفْلِحُونَ
Let there arise from you a nation inviting to good, enjoining what is right and forbidding what is wrong, and those will be the successful.
Surat Ali Imran 3:104
And Allah said:
كُنتُمْ خَيْرَ أُمَّةٍ أُخْرِجَتْ لِلنَّاسِ تَأْمُرُونَ بِالْمَعْرُوفِ وَتَنْهَوْنَ عَنِ الْمُنكَرِ وَتُؤْمِنُونَ بِاللَّهِ
You are the best nation produced for mankind. You enjoin what is right and forbid what is wrong and believe in Allah.
Surat Ali Imran 3:110
And Allah said:
خُذِ الْعَفْوَ وَأْمُرْ بِالْعُرْفِ وَأَعْرِضْ عَنِ الْجَاهِلِينَ
Show forgiveness, enjoin what is good, and turn away from the ignorant.
Surat al-A’raf 7:199
And Allah said:
وَالْمُؤْمِنُونَ وَالْمُؤْمِنَاتُ بَعْضُهُمْ أَوْلِيَاءُ بَعْضٍ يَأْمُرُونَ بِالْمَعْرُوفِ وَيَنْهَوْنَ عَنِ الْمُنكَرِ وَيُقِيمُونَ الصَّلَاةَ وَيُؤْتُونَ الزَّكَاةَ وَيُطِيعُونَ اللَّهَ وَرَسُولَهُ ۚ أُولَٰئِكَ سَيَرْحَمُهُمُ اللَّهُ إِنَّ اللَّهَ عَزِيزٌ حَكِيمٌ
The believing men and believing women are allies of one another. They enjoin what is right and forbid what is wrong and establish prayer and give charity and obey Allah and His Messenger. Allah will have mercy upon them. Verily, Allah is Almighty and Wise.
Surat at-Tawba 9:71
And Allah said:
لُعِنَ الَّذِينَ كَفَرُوا مِن بَنِي إِسْرَائِيلَ عَلَىٰ لِسَانِ دَاوُودَ وَعِيسَى ابْنِ مَرْيَمَ ذَٰلِكَ بِمَا عَصَوا وَّكَانُوا يَعْتَدُونَ كَانُوا لَا يَتَنَاهَوْنَ عَن مُّنكَرٍ فَعَلُوهُ لَبِئْسَ مَا كَانُوا يَفْعَلُونَ
Cursed by the tongue of David and of Jesus the son of Mary were those who disbelieved among the children of Israel. That was because they disobeyed and transgressed. They would not prevent one another from the wrongdoing they did. How evil was that which they were doing.
Surat al-Ma’idah 5:78-79
And Allah said:
وَقُلِ الْحَقُّ مِن رَّبِّكُمْ ۖ فَمَن شَاءَ فَلْيُؤْمِن وَمَن شَاءَ فَلْيَكْفُرْ
Say: The truth is from your Lord, so whoever wills let him believe, and whoever wills let him disbelieve.
Surat al-Kahf 18:29
And Allah said:
فَاصْدَعْ بِمَا تُؤْمَرُ وَأَعْرِضْ عَنِ الْمُشْرِكِينَ
Then declare what you are commanded and turn away from the idolaters.
Surat al-Hijr 15:94
And Allah said:
فَلَمَّا نَسُوا مَا ذُكِّرُوا بِهِ أَنجَيْنَا الَّذِينَ يَنْهَوْنَ عَنِ السُّوءِ وَأَخَذْنَا الَّذِينَ ظَلَمُوا بِعَذَابٍ بَئِيسٍ بِمَا كَانُوا يَفْسُقُونَ
When they forgot that by which they had been reminded, We saved those who had forbidden evil and seized those who wronged with a terrible punishment because they were defiantly disobedient.
Surat al-A’raf 7:165
Abu Sa’eed Al-Khudr, RadiyAllahu Anhu,i reported: The Messenger of Allah, SallAllahu Alaihi Wa Sallam, said:
مَنْ رَأَى مِنْكُمْ مُنْكَرًا فَلْيُغَيِّرْهُ بِيَدِهِ فَإِنْ لَمْ يَسْتَطِعْ فَبِلِسَانِهِ فَإِنْ لَمْ يَسْتَطِعْ فَبِقَلْبِهِ وَذَلِكَ أَضْعَفُ الْإِيمَانِ
Whoever among you sees evil should change it with his hand. If he is unable to do so, then with his tongue. If he is unable to do so, then with his heart and that is the weakest level of faith.

Ibn Mas’ud, RadiyAllahu Anhu, reported: The Messenger of Allah, SallAllahu Alaihi Wa Sallam, said:
مَا مِنْ نَبِيٍّ بَعَثَهُ اللَّهُ فِي أُمَّةٍ قَبْلِي إِلَّا كَانَ لَهُ مِنْ أُمَّتِهِ حَوَارِيُّونَ وَأَصْحَابٌ يَأْخُذُونَ بِسُنَّتِهِ وَيَقْتَدُونَ بِأَمْرِهِ ثُمَّ إِنَّهَا تَخْلُفُ مِنْ بَعْدِهِمْ خُلُوفٌ يَقُولُونَ مَا لَا يَفْعَلُونَ وَيَفْعَلُونَ مَا لَا يُؤْمَرُونَ فَمَنْ جَاهَدَهُمْ بِيَدِهِ فَهُوَ مُؤْمِنٌ وَمَنْ جَاهَدَهُمْ بِلِسَانِهِ فَهُوَ مُؤْمِنٌ وَمَنْ جَاهَدَهُمْ بِقَلْبِهِ فَهُوَ مُؤْمِنٌ وَلَيْسَ وَرَاءَ ذَلِكَ مِنْ الْإِيمَانِ حَبَّةُ خَرْدَلٍ
Allah did not send any Prophet in the nations before me except that he was given disciples and companions who followed his way and obeyed his command. Then, after them came their successors who said what they did not practice and who practiced what they were not commanded. He who strove against them with his hand was a believer, and he who strove against them with his tongue was a believer, and he who strove against them with his heart was a believer; beyond that there is no faith even the size of a mustard seed.

Ubadah ibn As-Samit, RadiyAllahu Anhu, reported:
بَايَعْنَا رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَلَى السَّمْعِ وَالطَّاعَةِ فِي الْعُسْرِ وَالْيُسْرِ وَالْمَنْشَطِ وَالْمَكْرَهِ وَعَلَى أَثَرَةٍ عَلَيْنَا وَعَلَى أَنْ لَا نُنَازِعَ الْأَمْرَ أَهْلَهُ وَعَلَى أَنْ نَقُولَ بِالْحَقِّ أَيْنَمَا كُنَّا لَا نَخَافُ فِي اللَّهِ لَوْمَةَ لَائِمٍ
We pledged allegiance to the Messenger of Allah, SallAllahu Alaihi Wa Sallam, pledging to listen and obey in hardship and in ease, in pleasure and displeasure even if someone is wrongly favored over us, and pledging not to dispute the rule of those in authority and that we should speak the truth wherever we are and not to fear those who blame us regarding Allah.

An-Nu’man ibn Basheer, RadiyAllahu Anhu, reported: The Prophet, SallAllahu Alaihi Wa Sallam, said:
مَثَلُ الْقَائِمِ عَلَى حُدُودِ اللَّهِ وَالْوَاقِعِ فِيهَا كَمَثَلِ قَوْمٍ اسْتَهَمُوا عَلَى سَفِينَةٍ فَأَصَابَ بَعْضُهُمْ أَعْلَاهَا وَبَعْضُهُمْ أَسْفَلَهَا فَكَانَ الَّذِينَ فِي أَسْفَلِهَا إِذَا اسْتَقَوْا مِنْ الْمَاءِ مَرُّوا عَلَى مَنْ فَوْقَهُمْ فَقَالُوا لَوْ أَنَّا خَرَقْنَا فِي نَصِيبِنَا خَرْقًا وَلَمْ نُؤْذِ مَنْ فَوْقَنَا فَإِنْ يَتْرُكُوهُمْ وَمَا أَرَادُوا هَلَكُوا جَمِيعًا وَإِنْ أَخَذُوا عَلَى أَيْدِيهِمْ نَجَوْا وَنَجَوْا جَمِيعًا
The parable of the one who observes the limits prescribed by Allah and the one who transgresses them is the likeness of people who board a ship after casting lots. Some of them are in its lower deck and others are in its upper deck. Those in the lower deck, when they need water, go to the upper deck and say: If we make a hole in the bottom of the ship, we will not harm you. If those in the upper deck leave them to carry out their plan, they will all be drowned, but if they stop them, then all of them will be safe.

Umm Salamah, RadiyAllahu Anha, reported: The Messenger of Allah, SallAllahu Alaihi Wa Sallam, said:
سَتَكُونُ أُمَرَاءُ فَتَعْرِفُونَ وَتُنْكِرُونَ فَمَنْ عَرَفَ بَرِئَ وَمَنْ أَنْكَرَ سَلِمَ وَلَكِنْ مَنْ رَضِيَ وَتَابَعَ
There will be rulers from whom you will see both goodness and corruption. One who recognizes their evil and hates it will maintain his innocence; but one who is pleased with it and follows them will be sinful.
It was said, “Shall we not fight them?” The Prophet said:
لَا مَا صَلَّوْا
No, as long as they pray.

Zainab bint Jahsh, RadiyAllahu Anhu, reported: The Prophet, SallAllahu Alaihi Wa Sallam, came to visit me one day while he was frightened and he said:
لَا إِلَهَ إِلَّا اللَّهُ وَيْلٌ لِلْعَرَبِ مِنْ شَرٍّ قَدْ اقْتَرَبَ فُتِحَ الْيَوْمَ مِنْ رَدْمِ يَأْجُوجَ وَمَأْجُوجَ مِثْلُ هَذِهِ
There is no God but Allah! Woe to the Arabs because of an evil that is drawing near! Today an opening of this size has been made in the barrier restraining Gog and Magog.
He made a circle with this thumb and finger. I said, “O Messenger of Allah, will we perish while there are still righteous people among us?” The Prophet said:
نَعَمْ إِذَا كَثُرَ الْخَبَثُ
Yes, if wickedness prevails.
