40 Ahadees ki Fazilat :


Hazrat e Syeduna Abu Darda R.A farmate hain k Rehmat-e-Alam S.A.W se Arz ki gae k us Ilm ki had kya hai jahan Insan pohanchay to Aalim ho?
Aap ne irshad farmaya : Jo meri Ummat per 40 Ahkam-e-Deen ki Ahadees Hifz kare usay Allah Faqeeh uthae ga aur Qiyamat k Din main uska Shafi aur Gawah hoon ga.

(Mishkat-ul-Masabih, Hadis 257, Jild 2, Page 68)
