Shaykh al-Islam Mawlana Sayyid Husayn Ahmad Madani (may Allah shower His mercy upon him) advised: 

‘‘It is not obligatory to give bay‘ah [to a shaykh of tasawwuf], nor does salvation depend on it. Hundreds of thousands of Muslims do not give bay‘ah; will they not be forgiven [for their sins] in the Divine Court? Therefore, you should not be hasty. Continue to search for a guide and pious person who is accomplished in shari‘ah and tariqah. If you find one who fulfils these criteria, give bay‘ah to him. Otherwise, everything lies in following our illustrious Master, the honourable Leader of all creation (blessings and peace upon him). Occupy yourself with this.’’
