3. 2:68 قَالُوا۟ ٱدْعُ لَنَا رَبَّكَ يُبَيِّن لَّنَا مَا هِىَ قَالَ إِنَّهُۥ يَقُولُ إِنَّهَا بَقَرَةٌ لَّا فَارِضٌ وَلَا بِكْرٌ عَوَانٌۢ بَيْنَ ذَٰلِكَ فَٱفْعَلُوا۟ مَا تُؤْمَرُونَ

   O you who believe! do not violate the signs appointed by Allah nor the sacred month, nor (interfere with) the offerings, nor the sacrificial animals with garlands, nor those going to the sacred house seeking the grace and pleasure of their Lord; and when you are free from the obligations of the pilgrimage, then hunt, and let not hatred of a people-- because they hindered you from the Sacred Masjid-- incite you to exceed the limits, and help one another in goodness and piety, and do not help one another in sin and aggression; and be careful of (your duty to) Allah; surely Allah is severe in requiting (evil).
   

6. 7:128 قَالَ مُوسَىٰ لِقَوْمِهِ ٱسْتَعِينُوا۟ بِٱللَّهِ وَٱصْبِرُوٓا۟ إِنَّ ٱلْأَرْضَ لِلَّهِ يُورِثُهَا مَن يَشَآءُ مِنْ عِبَادِهِۦ وَٱلْعَٰقِبَةُ لِلْمُتَّقِينَ

   Musa said to his people: Ask help from Allah and be patient; surely the land is Allah's; He causes such of His servants to inherit it as He pleases, and the end is for those who guard (against evil).
   

7. 12:18 وَجَآءُو عَلَىٰ قَمِيصِهِۦ بِدَمٍ كَذِبٍ قَالَ بَلْ سَوَّلَتْ لَكُمْ أَنفُسُكُمْ أَمْرًا فَصَبْرٌ جَمِيلٌ وَٱللَّهُ ٱلْمُسْتَعَانُ عَلَىٰ مَا تَصِفُونَ

   And they brought his shirt with false blood upon it. He said: Nay, your souls have made the matter light for you, but patience is good and Allah is He Whose help is sought for against what you describe.

    And those who disbelieve say: This is nothing but a lie which he has forged, and other people have helped him at it; so indeed they have done injustice and (uttered) a falsehood.
