It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that once he heard the Noble Prophet (peace and blessings be upon him) saying: Is there any man who will acquire one word or two, three, four, or five words that have been made obligatory by Allah and His Messenger, place them in the corner of his sheet, learn them, and teach them to others? I presented myself. The Noble Prophet (peace and blessings be upon him) said: Then spread your cloth. So I spread my cloth. The Noble Prophet (peace and blessings be upon him) narrated the hadith and said: Attach it to your body. I pressed it to my chest. Because of this, I hope that after this, I have never forgotten any hadith that I heard from the Noble Prophet (peace and blessings be upon him).
