Everything in this book that is narrated from Abdullah ibn Fadalah has been transmitted by me from Muhammad ibn Musa ibn Al-Mutawakkil - may Allah (swt) be pleased with him - from Ali ibn Al-Husayn Al-Sa'dabadi, from Ahmad ibn Muhammad ibn Khalid, from his father, from Muhammad ibn Sinan, from Bandar ibn Hammad, from Abdullah ibn Fadalah.
