My Sheikh Yunus Jaunpuri once said that, Gujrati, Bihari & Bangali express the fact that they have khilafat, these things were not found in the elders, the elders used to hide their khilafat. Anybody wishing to verify how khilafat was hidden should read Maulana Zakariyas khilafat incident and also of Mufti Mehmud Gangohi.
