Imam Salahud Deen As Safadi (D. 764AH): the student of ibn Taymiyya, said in his biography of Ibn Taymiyyah in his book, “Al Waafi bil Wafayaat”:
:وقال الصفدي أثناء ترجمة ابن تيمية في الوافي بالوفيات
وحكى لي عنه الشيخ شمس الدين ابن قيم الجوزية قال: كان صغيرا عند بني المنجا فبحث معهم فادعوا شيئا أنكره فأحضروا النقل فلما وقف عليه ألقى المجلد من يده غيظا، فقالوا له: ما أنت إلا جريء ترمي المجلد من يدك وهو كتاب علم، فقال سريعا: أيما خير أنا أو موسى? فقالوا موسى، فقال: أيما خير هذا الكتاب أو ألواح الجوهر التي كان فيها العشر كلمات? قالوا: الألواح، فقال: إن موسى لما غضب ألقى الألواح من يده، أو كما قال. أهـــ
“Ash Shaikh Shamsud Deen Ibnu Qayyim Al Jawziyyah told me about him saying: When he was young he was in the company of (the Hanbali family of Scholars) Banu Al Munajja, so he debated with them. So they claimed something he denied. Then they brought the quote. When he saw it, he threw the book down in anger. They said to him, “You sure are bold to throw down the book when it is a book of Religious Knowledge!” Whereupon he immediately said, “Who is better, me or Musa?” So they said, “Musa”. Then he said, “Which is better, this book or the Tablets containing the Ten Commandments?” They said, “The Tablets.” So Ibn Taymiyyah said, “Well, when Musa became angry he threw the Tablets down!” – or something to this effect”
This quote can also be found translated into English on page 110 and 111 of “Al Albani Unveiled”, a book definitely worth owning.
