Shuru Allah k Naam se: Aur ham ne aap se Pehle bhi apne Rasoolon ko un ki Qoum ki Taraf bheja wo un k paas dalilain layen, Phir ham ne Gunhgaron se inteqam liya, ham par Momino ki madat karna lazim hai.(Surah:Al-Rum, Surah No:30, Aayat No:47)

We did indeed send, before thee, messengers to their (respective) peoples, and they came to them with Clear Signs: then, to those who transgressed, we meted out Retribution: and it was due from us to aid those who believed. (The Holly Quran - Chapter 30 , Al-Rum - Verse 47)
