I have prepared for My pious servants which the eye has seen not, and the ear has heard not and no human heart has ever perceived such bounties leaving aside those about which Allah has informed you. He then recited:" No soul knows what comfort has been hidden for thein". (Using translation from Muslim 2824c)
قَالَ رَسُولُ اللهِ ﷺ يَقُولُ اللهُ تَعَالَى أَعْدَدْتُ لِعِبَادِيَ الصَّالِحِينَ مَا لَا عَيْنٌ رَأَتْ وَلَا أُذُنٌ سَمِعَتْ وَلَا خَطَرَ عَلَى قَلْبِ بَشَرٍ ذُخْرًا مِنْ بَلْهَ مَا أَطْلَعَكُمْ عَلَيْهِ ثُمَّ قَرَأَ {فَلَاتَعْلَمُ نَفْسٌ مَا أُخْفِيَ لَهُمْ مِنْ قُرَّةِ أَعْيُنٍ} [السجدة 17]
