Israf

So in that hut, in that barn, he was literally writing down knowledge.

Shaykh al-Albani, rahimahullah, He said, throwing away a tiny piece of paper is Israf.

Because one tiny piece of paper can contain, you can write a hadith on it.

So when you would throw away, when the students would see that you throw away a piece of paper, said this is not the sunnah of our Shaykh.
