Hazur pak p.b.u.h ka khwab mubarik

Narrated Samura (RA): The Prophet p.b.u.h said, “Last night two men came to me (in a dream) and made me ascend a tree and then admitted me into a better and superior house, better of which I have never seen. One of them said, ‘This house is the house of martyrs.”
