Ustad Naseer ud Din Saami narrates Ustad Sardar Khan’s trip to Karachi in 1958 where in two separate gatherings, his singing reduced the audience to tears – such was the power of his singing.

From 1960 – 1963 Ustad Naseer ud Din Saami, the current flag bearer of the Qawwal Bacha/Delhi Gharana also learnt from him. This was arranged by Ustad Saami’s teacher, Ustad Raziuddin Khan who was the nephew of Ustad Sardar Khan.

In 1963, one day before his passing on 19th Ramzan at the age of 75, he sang Raag Hussaini Kanra on Radio Lahore. Ustad Raziuddin Khan took him to Karachi after his passing where he is buried. His son M. Ibrahim Khan did not continue in the singing tradition of his father and Gharana.
