40 Hadith Qudsi
On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (peace and blessings of Allah be upon him) said:
"Allah said:
'I have prepared for My righteous servants what no eye has seen and no ear has heard, nor has it occurred to the human heart.'"
Thus recite if you wish (1): "And no soul knows what joy for them (the inhabitants of Paradise) has been kept hidden (Qur'an Chapter 32 Verse 17)."
(1) The words "Thus recite if you wish" are those of Abu Hurayrah.
[Bukhari, Muslim, at-Tirmidhi and Ibn Majah.]
