Mawlana Sayyid Mahbub Ridwi writes:
His (Mawlana Ahmad ‘Ali Saharanpuri’s) handwriting was very clear. Mawlana Khalil Ahmad Anbethwi (Saharanpuri) was in possession of a complete manuscript of [Sunan] Abi Dawud which was handwritten by Muhaddith [Ahmad ‘Ali] Saharanpuri. This is the very same manuscript that Mawlana Khalil Ahmad Saharanpuri would keep in front of him whilst writing Badhl al-Majhud.
