By the (Winds) that scatter broadcast;
And those that lift and bear away heavy weights;
And those that flow with ease and gentleness;
And those that distribute and apportion by Command -
Verily that which are promised is true; [Qur'an 51:1-5]

Narrated 'Abdullah: The best talk (speech) is Allah's Book 'Quran), and the best way is the way of Muhammad(PBUH), and the worst matters are the heresies (those new things which are introduced into the religion); and whatever you have been promised will surely come to pass, and you cannot escape (it).
