يَا أَخَا كَلْب، لَيْسَ هُوَ بِعِلْمِ غَيْب، وَإِنَّمَا هُوَ تَعَلُّمٌ مِنْ ذِي عِلْم، وَإِنَّمَا عِلْمُ الْغَيْبِ عِلْمُ السَّاعَةِ، وَمَا عَدَّدَهُ اللهُ سُبْحَانَهُ بِقَوْلِهِ: ﴿إِنَّ اللهَ عِندَهُ عِلْمُ السَّاعَةِ وَيُنَزِّلُ الْغَيْثَ وَيَعْلَمُ مَا فِي الْأَرْحَامِ ۖ وَمَا تَدْرِي نَفْسٌ مَّاذَا تَكْسِبُ غَدًا ۖ وَمَا تَدْرِي نَفْسٌ بِأَيِّ أَرْضٍ تَمُوتُ..﴾ الاية.
O brother of Kalb! This is not knowledge of hidden things (‘ilmu’l-ghayb ), [3] these matters have been acquired from him (namely in Prophet) who knew them. As regard knowledge of hidden things, that means knowledge of the Day of Judgement, and the things covered by Allāh in the verse : Verily, Allāh is He with Whom is the knowledge of the Hour . . . (Qur’ān, 31:34)
