Sahl bin Sa'd (May Allah be pleased with him) said:
I was in the company of the Prophet (ﷺ). He gave a description of Jannah and concluded with these words, "There will be bounties which no eye has seen, no ear has heard and no human heart has ever perceived." He (ﷺ) then recited this Verse:"Their sides forsake their beds, to invoke their Rubb in fear and hope, and they spend (in charity in Allah's Cause) out of what We have bestowed on them. No person knows what is kept hidden for them of joy..." (32:16,17)[Al-Bukhari].
