1. 3:173Aali Imran
   ٱلَّذِينَ قَالَ لَهُمُ ٱلنَّاسُ إِنَّ ٱلنَّاسَ قَدۡ جَمَعُواْ لَكُمۡ فَٱخۡشَوۡهُمۡ فَزَادَهُمۡ إِيمَٰنٗا وَقَالُواْ حَسۡبُنَا ٱللَّهُ وَنِعۡمَ ٱلۡوَكِيلُ
   Those unto whom men said: Lo! the people have gathered against you, therefor fear them. (The threat of danger) but increased the faith of them and they cried: Allah is Sufficient for us! Most Excellent is He in Whom we trust!

   Some of the idolaters said to them that the Quraysh, led by Abū Sufyān, had come together in great numbers to fight against them and to finish them off, warning them against meeting them. But their words and attempts to scare them only increased their reliance on Allah and their trust in His promise.

2. 4:81An-Nisa
   وَيَقُولُونَ طَاعَةٞ فَإِذَا بَرَزُواْ مِنۡ عِندِكَ بَيَّتَ طَآئِفَةٞ مِّنۡهُمۡ غَيۡرَ ٱلَّذِي تَقُولُۖ وَٱللَّهُ يَكۡتُبُ مَا يُبَيِّتُونَۖ فَأَعۡرِضۡ عَنۡهُمۡ وَتَوَكَّلۡ عَلَى ٱللَّهِۚ وَكَفَىٰ بِٱللَّهِ وَكِيلًا
   And they say: (It is) obedience; but when they have gone forth from thee a party of them spend the night in planning other than what thou sayest. Allah recordeth what they plan by night. So oppose them and put thy trust in Allah. Allah is sufficient as Trustee.
   In context

   The hypocrites say to you, ‘We follow your instruction and we will act with obedience’. Yet when they leave you, a group of them secretly plan the opposite of what they said to you. Allah knows their planning and He will recompense them accordingly. So turn away from them and pay no attention, as they will not harm you at all.

   يَـٰٓأَهۡلَ ٱلۡكِتَٰبِ لَا تَغۡلُواْ فِي دِينِكُمۡ وَلَا تَقُولُواْ عَلَى ٱللَّهِ إِلَّا ٱلۡحَقَّۚ إِنَّمَا ٱلۡمَسِيحُ عِيسَى ٱبۡنُ مَرۡيَمَ رَسُولُ ٱللَّهِ وَكَلِمَتُهُۥٓ أَلۡقَىٰهَآ إِلَىٰ مَرۡيَمَ وَرُوحٞ مِّنۡهُۖ فَـَٔامِنُواْ بِٱللَّهِ وَرُسُلِهِۦۖ وَلَا تَقُولُواْ ثَلَٰثَةٌۚ ٱنتَهُواْ خَيۡرٗا لَّكُمۡۚ إِنَّمَا ٱللَّهُ إِلَٰهٞ وَٰحِدٞۖ سُبۡحَٰنَهُۥٓ أَن يَكُونَ لَهُۥ وَلَدٞۘ لَّهُۥ مَا فِي ٱلسَّمَٰوَٰتِ وَمَا فِي ٱلۡأَرۡضِۗ وَكَفَىٰ بِٱللَّهِ وَكِيلٗا
   O People of the Scripture! Do not exaggerate in your religion nor utter aught concerning Allah save the truth. The Messiah, Jesus son of Mary, was only a messenger of Allah, and His word which He conveyed unto Mary, and a spirit from Him. So believe in Allah and His messengers, and say not "Three" - Cease! (it is) better for you! - Allah is only One Allah. Far is it removed from His Transcendent Majesty that He should have a son. His is all that is in the heavens and all that is in the earth. And Allah is sufficient as Defender.
   In context

   Say, O Messenger, to the Christians who received the Gospel: Do not overstep the limits in your religion and do not say anything but the truth about Allah in relation to Jesus. The Messiah, Jesus, son of Mary, is only Allah’s messenger sent with the truth. He created him by His word which He sent with Gabriel to Mary, which was the word ‘Be’, and he became.
