Assalaam u alaikum wr wb, Indeed Mufti sahib is very eassy to contact there are allways 2 numbers that Mufti sahib d.b will give one is his house number and the second one is Madrassah number. Masha Allah very very humble when you visit him in the madrassah you would think he's a normall teacher. Masha Allah Mufti sahib stayed for arround 14 or 17 years in the sohbah of Hazrat MaseehulUmmah r.a one of the most trusted khulafa of Hazrat Haheemulummah r.a! He has been teaching saheehulbukhaari for at least 20 years Masha Allah. I'm not telling you about Mufti sahib because i'm bayt to him or anything just because want to advice what i think is beneficcial for you . For the rest Allah swt knows best. JazakAllah
