An aspirant asked Hazrat Moulana Mohammad Taqi Usmani sahib db, was it inappropriate not to visit other shuyukh after finally selecting Hazrat db as Sheikh.
Hazrat db replied, visiting other shuyukh occasionally to receive their prayers (dua) and advice is appropriate. One should not avoid this. However, in your personal spiritual matters consultation and guidance should be only taken from the Sheikh you have selected for self-reformation (islah).
