Sayyidi wa sanadi Shaikh Mufti Mohammad Taqi Usmani (Allah preserve him) wrote in the obituary of Shaikh Nawab Eshrat Ali Khan Qaiser (Allah have mercy on him),

‘Recently (prior to his death) he confided in me and said, all praise is for Allah, I do not recall leaving a salah with jama’ah (congregation) for the previous fifty two years.’
