Clarification of the Transmission Chain to Wahb Ibn Wahb

Everything in this book that is narrated from Wahb ibn Wahb has been transmitted by me from my father and from Muhammad ibn Al-Hasan - may Allah (swt) be pleased with them both - from Sad ibn Abdullah, from Ahmad ibn Muhammad ibn Khalid, from his father, from Abu Al-Bakhtari Wahb ibn Wahb Al-Qadi Al-Qurashi.
