Appears 3 times in the Quran.
5:19 يَٰٓأَهْلَ ٱلْكِتَٰبِ قَدْ جَآءَكُمْ رَسُولُنَا يُبَيِّنُ لَكُمْ عَلَىٰ فَتْرَةٍ مِّنَ ٱلرُّسُلِ أَن تَقُولُوا۟ مَا جَآءَنَا مِنۢ بَشِيرٍ وَلَا نَذِيرٍ فَقَدْ جَآءَكُم بَشِيرٌ وَنَذِيرٌ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ
O followers of the Book! indeed Our Messenger has come to you explaining to you after a cessation of the (mission of the) messengers, lest you say: There came not to us a giver of good news or a warner, so indeed there has come to you a giver of good news and a warner; and Allah has power over all things.
They glorify (Him) by night and day; they are never languid.
It shall not be abated from them and they shall therein be despairing.
