Key Verses

1. 47:18Muhammad
   فَهَلۡ يَنظُرُونَ إِلَّا ٱلسَّاعَةَ أَن تَأۡتِيَهُم بَغۡتَةٗۖ فَقَدۡ جَآءَ أَشۡرَاطُهَاۚ فَأَنَّىٰ لَهُمۡ إِذَا جَآءَتۡهُمۡ ذِكۡرَىٰهُمۡ
   Await they aught save the Hour, that it should come upon them unawares? And the beginnings thereof have already come. But how, when it hath come upon them, can they take their warning?
   In context

   Are the disbelievers waiting for anything but the hour to come on them suddenly without their having any prior knowledge of it? Its signs have already come, such as the mission of the Prophet (peace be upon him) and the splitting of the moon. How will they then take heed when the hour comes? It is unlikely that the reminder will be of benefit to them.

2. 81:4At-Takwir
   وَإِذَا ٱلۡعِشَارُ عُطِّلَتۡ
   And when the camels big with young are abandoned,
   In context

   When pregnant she-camels, which were their most valuable wealth, are neglected by being abandoned by their owners.
