On taking the paper, I saw the following written within it:
I had a dream, during the night, in which it seemed as if I was being told, “This is Rasulullah (sallallahu ‘alaihi wasallam) in the Musjid.” I thus proceeded to the Musjid where I found that the corner of the blessed grave of Rasulullah (sallallahu ‘alaihi wasallam) had opened, and Rasulullah (sallallahu ‘alaihi wasallam) was seated, while the people around him were requesting, “O Rasul of Allah (sallallahu ‘alaihi wasallam)! Advise us!” Rasulullah (sallallahu ‘alaihi wasallam) replied, “I have buried a treasure beneath the Mimbar, and I instructed Imaam Maalik (rahimahullah) to distribute it among the people, so go to Imaam Maalik (rahimahullah).” Hearing this, the people began to disperse. As they left, one of them asked the others, “What do you think Imaam Maalik (rahimahullah) will do?” He replied, “Imaam Maalik (rahimahullah) will fulfill the instruction of Rasulullah (sallallahu ‘alaihi wasallam).”
On learning of this blessed dream, Imaam Maalik (rahimahullah) became extremely affected and began to weep. When I thereafter departed, I left him in the very same condition of weeping.”
Note: ‘Treasure’ referred to the Mubaarak Ahaadith of Rasulullah (sallallahu ‘alaihi wasallam) and the knowledge of Deen.
