وَإِذَا جَآءَهُمْ أَمْرٌۭ مِّنَ ٱلْأَمْنِ أَوِ ٱلْخَوْفِ أَذَاعُوا۟ بِهِۦ ۖ وَلَوْ رَدُّوهُ إِلَى ٱلرَّسُولِ وَإِلَىٰٓ أُو۟لِى ٱلْأَمْرِ مِنْهُمْ لَعَلِمَهُ ٱلَّذِينَ يَسْتَنۢبِطُونَهُۥ مِنْهُمْ ۗ وَلَوْلَا فَضْلُ ٱللَّهِ عَلَيْكُمْ وَرَحْمَتُهُۥ لَٱتَّبَعْتُمُ ٱلشَّيْطَٰنَ إِلَّا قَلِيلًۭا
And if any tidings, whether of safety or fear, come unto them, they noise it abroad, whereas if they had referred it to the messenger and to such of them as are in authority, those among them who are able to think out the matter would have known it. If it had not been for the grace of Allah upon you and His mercy ye would have followed Satan, save a few (of you).
Surah An-Nisaa(4:83)
