Allah accepts the repentance of the servant so long as his soul has not arrived at his throat. (Tirmidhi)

Say what you wish in abuse of me, for my silence towards the idiot is indeed an answer. I am not at a loss for a response but rather, It does not befit the lion to answer the dogs. - Imam Ash-Shafi'i (Rahimahullah).

Learn to be quiet just as you learn to talk, because if talking guides you, being quiet protects you. By being quiet, you attain two characteristics: you are able to take knowledge from those more knowledgeable than you, and you are able to repel the ignorance of those more ignorant than you.

The only thing you cant recycle is time..
