وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : إِنَّ اللَّهَ عَزَّ وَجَلَّ قَالَ : " أَعْدَدْتُ لِعِبَادِي الصَّالِحِينَ مَا لَا عَيْنٌ رَأَتْ ، وَلَا أُذُنٌ سَمِعَتْ ، وَلَا خَطَرَ عَلَى قَلْبِ بَشَرٍ " .
And the Noble Prophet, peace and blessings be upon him, said: Allah, the Exalted, says: I have prepared for My righteous servants such things as no eye has seen, no ear has heard, and no human heart has ever conceived.
